Hi there this is my kind of thread.
From 8bp you definitely ought to check out x|k, lo-bat, goto80, and psilodump (my favorite artist, period, btw)
Also if you hadn't noticed, virt has an album up on there now too. Get that one plus his first two on archive.org
I also suggest herbert weixelbaum, and for those of you who don't know, shnabubula also made some chiptunes, which are quite good. I'll upload those somewhere and get back to you, considering his site is unavailable at the moment.
Be sure to buy a copy of 8bp's 50th release too, because barring two tracks that I dont particularly care for, it's full of fantastic music.
EDIT: Here's them Shnabubula tracks
