Not a meme

From tapas:

Virgin Records was running a nifty puzzle promotion a while ago, in which entrants were asked to find the dozens of band names represented in this picture. I've seen various numbers (65, 72, 75) for the total count, of which I've found about 60 (two of which I had help on, and some of which I'm not too sure about). ( Click for spoilers! )

Obviously the answers are findable online, but I'm trying not to cheat yet. :) and now I've found them, more or less. Only two "duh!" moments. :) See my comment.
