Like most people I use digital for obvious reasons. Now, sound-wise, I prefer vinyl LP without any doubts.

I never bought digital music before and I do not plan to do so any time soon (or ever).
Physical media is superior in nearly every aspect, the only disadvantage I can think of is the huge amount of space it requires to handle a big collection.
I prefer CDs over anything else, because those provide the best quality. No, vinyl is not better, stop spreading this myth already (although I appreciate them too, of course, since they are beautiful objects).
Digital music lacks the artwork, the feeling, freedom (you cannot sell MP3s, can you) and of course the aforementioned quality. Even with FLAC files you are not on the safe side regarding this most important point, since it is very easy (and common) to convert bloody MP3 files into FLACs and the only way to identify those fake FLAC files is to examine them when they are on your hard drive, so you obviously have to buy them first.
So, a real collection for me, and digital stuff for you convenience lovers.

MP3's.

I don't have the space for anything else. Whenever it's an option I always go digital.

Needledrops. Quality needledrops. Yeah, it's like looking for a needle in haystack, with haystacks scattered in deep space.
Vinyls are great, but require some knowledge of their upkeep, there are many things vinyls don't like, buying used ones that aren't fubar'ed is blind luck. And them portable vinyl players are a no-no for my back.

With CDs, well, the mastering on mosts CD releases these days is abysmal. A shame really, given the capabilities of the digital medium. So consult thy Dr Loudness Wars for info.

if I had the space, I'd go vinyl without hesitation. I find I like everything about it better (artwork on album covers, inserts, the look and feel of the LP, and yes even the sound). But since I collect hardcover books and already don't have enough room, there;s just no way I'd start collecting LPs again. I'm by no means an audiophile so even though I tend to like the (IMO) richer, warmer sound of an LP, given the realities of life, I'd have to go with MP3.

When I can get a nice deal on an LP or a single (even if my player technically doesn't play singles) I'd like one, but common times I get CDs, most CDs sound better on a good sound system than MP3 files on the speakers I have for them. Also, burning music to CDs doesn't sound quite as good as a real, first print CD anyway, and then normally not as good as an LP can. I've got kind of a cheap record player (it's supposed to allow me to make MP3 files based on playing the record, but I just use it as a player) but Information Society's first album sounds better there than my MP3 files. Although, for ease of use, an MP3 player isn't bad and, unfortunately, most of my Japanese music has to be on MP3 (or else, I import the CD like with my B'z single). So, if possible/viable always go physical, if quality and collectivity are not prime for you, MP3 does nicely.

I used to have some vinyls and cd´s, but I dropped that for the convenience of digital files (with the FLAC format, there´s not that much lost in quality, although vinyl has a particular sound, not better or worse, something different, prone to bass that I love). But I´m full digital nowadays.

I love vinyl, but the high cost and space issue does become a problem. I still pick up a few each year.

I don't think I could get SNES music on a record, and even if I could, it wouldn't be a very efficient way of listening to it.

I never liked cassettes either, since it was guesswork most of the time. With digital media, you can track exactly where you want to be.

But I can't actually speak much on this subject since SPC (25.8%); NSF (24.1%); GBS (10.7%); MP3 (7.4%); Vorbis (3.8%); FLAC (0.9%); VGM (0.9%); KSS (0.5%); IT v2.00 (0.4%); PCM (0.4%); RIFF AM (0.2%); NSFE (0.2%); AAC (0.2%); MOD (0.2%); PSF (0.2%); XM v1.04 (0.2%); S3M (0.1%); WMA (0.1%); IT v1.00 (0.0%); RIFF AMFF (0.0%); Microsoft ADPCM (0.0%), etc.

I grew up with vinyl and I still don't get the reverence for the format. The pops, clicks, and scratches of records used to drive me up a wall. Not to mention the space the albums and even how much space a record player takes up. When cassettes came along, I was happy to move on to a more compact media...not to mention the ease at which to "pirate" music for the poor teenager I was. Then CD came along and offered the quality of vinyl, minus the pops, with a compact media, that didn't degrade or get easily damaged (like cassette) and I never looked back.

I still buy all my music on CD, rip the original wav file to my backup hard drive, and rip an mp3 at 320, and store the original CD in a box in the back of my closet. I use another format over mp3 if my mp3 player and car's audio system supported it.

What exactly is that chart all about?

well In my case I love buy music on CD-ROM (not on Vinyl LP), and when I export the CD in Itunes I use Itunes Loseless quality not the popular Acc itunes plus. some times I use FLAC Loseless format in my PC. the reason I never like Vinyl LP is for the little scrach sound and because these discs are really big and fragile...

I fondly remember both. When compact disc became a reality I never looked back.

There haven't been many good bands after Pink Floyd anyway, so....

For some reason, I seem to prefer gaming (and sometimes movie) music to real music, at least to that music I usually hear on the radio. Most "real" music just leaves me cold, just like someone was talking on the radio, while good gaming or movie music manages to raise all kinds of emotions inside me. I'm not sure why.

Nightwish sometimes manages to make some interesting tunes, I think their composer (Tuomas Holopainen) is brilliant. When I heard e.g. "The Poet and the Pendulum" the first few times (took a few times to really appreciate it), I think it easily shot to the top 10 or even top 5 tunes I've ever heard. That was interesting as I didn't use to like Nightwish earlier, at least back when Tarja Turunen was singing. I think that might be the reason, the singer is quite often in a too big role in "real music".

Oh, to the OP: I prefer digital format, just for convenience. Having my whole music collection always with me to play anywhere, without (DRM) restrictions? Count me in!

Nightwish are a great live band. I have had the pleasure of seeing them on their last two tours.

They are a band that really benefit from vinyl releases. Their last few albums have been so heavily over produced on cd I find it quite hard on the ears. A shame considering the music is fantastic.
