I am going to blow all of your minds.

Online video game playlist:
http://vip.aersia.net/vip.swf

Online anime playlist:
http://wap.aersia.net/wap.swf

The vidya playlist has a ton of songs (Changelog at http://vip.aersia.net/changelog.txt), and the anime playlist has quite a few less (http://wap.aersia.net/changelog.txt)

But wait, there's more! If you want to download the songs on there to listen to on mcp or MOC or your music player of choice, just run this command in your terminal while in the directory you want to dump songs into!

wget -r -l1 -H -t1 -nd -N -np -erobots=off -i http://vip.aersia.net/mu/

or, for animu musics,

wget -r -l1 -H -t1 -nd -N -np -erobots=off -i http://wap.aersia.net/mu/

They are .m4a files, so it may be  a bit cumbersome to play without proper plugins.

Enjoy.
