Well it doesn't really "matter." It's just my personal preference. I figure if I am going to mail 20 or so mix CDs, they may as well contain songs that aren't as well known (by my definition anyways - some may think an artist like SF59 are big). It's my own small way of helping smaller artists get more recognition I guess. It seems the point of these mix exchanges is usually to introduce folks to music they might not otherwise check out on their own. That's pretty much why I do it....and I like the prospect of getting introduced to stuff I'm not currently familiar with (which is a lot), but might like.
But if you absolutely feel "Paranoid Android" or "I Turn My Camera On" need to be on there...run with it.
