Anyone can answer but this would be especially useful if you actually lived in the 70s.

One is dead the other is thriving. You figure it out.

Born in 80 but 70's rock is the obvious choice. Lot of great bands started that decade.

Guys, guys, you're being marzooker'd.

I know but I really don't care anymore.

Disco is dead.
70's rock continues to flourish. A lot of the bands (Sabbath, Aerosmith, RUSH, Fleetwood Mac) continue to put out good music and tour. The ones who are defunct (Zeppelin) continue to heavily influence up and coming bands and dominate rock station airwaves. Disco is a fart in the wind. You may get a whiff of it now then but that's it, nothing lasting.

it never died for me, still listen to it regularly. Still plays on the "Gold" radio station :D

Remind me never to come over. :P

Why was disco so hated? Especially coming from rock/metal musicians/fans?

I don't think it was hated but looked upon more of as a fad. It wasn't it's own genre ie rock, jazz, blues. There was also a vibe of pretention, selfishness, and delusion that went along with it that looking back makes a lot of people feel guilty about embracing it. I can only speak for the States but it's almost like this country was trying to get passed all the strife of the 60's by pretending it never happened. Of course, I may be just talking out of my ass.

Disco is not dead, at all- check out any nu-disco stuff, and all of its iterations.

The first episode in this movie at least tried to explain it quickly:

That said, there are some disco songs to which I find enjoyable to listen, but overall: rock. I guess I consider disco to be like modern dance music: it is not so much meant to be listened to, but to be danced with. Ok then, I don't consider tango music that interesting either to listen to, but it is needed in order to dance tango.

Then again, nowadays I don't get it when I turn on the local rock radio station, they seem to always play only the same dozen or so rock songs, and ones that I don't like that much. Rolling Stones sucks, "I can get no satisfaction" because your music sucks so much! Yet they keep playing that too. ACDC sucks too, I always consider it as the Australian Hurriganes.

And there hardly ever seems to be newer rock songs in there. The few that are sometimes played there are poo, like Nickelback. Oh well, I guess I keep listening to my Pink Floyd, Supertramp, The Who and Jethro Tull CDs instead.

Love you. ;)
