There are many that I really like and fancy covering (especially some of my own!

The Amiga had a genre all to itself (a bit like C64 but more so) of music called "Demo-music" - and a lot of it was bloody terrible.
I'm also going through an anti-amiga phase unfairly due to the wonders of Deliplayer (player that plays every Amiga audio format) mainly due to the fact it plays Amiga stuff far to accurately. By that I mean that it seems to output at 28khz 8bit... and it sounds just like an Amiga.. horrible 8-bit scratchy ringing samples... everything that I hated the most when composing on the Amiga. Use Winamp (with appropriate plugin) or Modplugplayer and their anti-aliased PC wonderment does ... er.. wonders!
Aside from all that tho, and aside from covering my own mods I'm likely to begin work on one or more of the Desert Dream themes, Macrocosm by Firefox+tip and who knows what else.
