I noticed it more and more going through the first 1/4 of the game that mission titles seemed to be very similar, if not spot on, to some of the best rock/pop-rock songs ever made.
Now closer to ~50hrs in, going back through the Journal's mission lists I see a large number of them are named this way and it includes many of my favorite songs that were never produced as singles or had much radio airplay.

from The Doors, The Beatles, The Turtles, David Bowie, Talking Heads, Tracy Chapman, Aerosmith and many more; some awesome deep album tracks and some more well known titles too.

too bad they didn't include all or any of these songs in the in-game soundtrack, there's wayy too much really cheesy/crappy stuff on the available radio stations.
it would be nice if we could add our own custom radio playlists.
