As for my contributions:
There She Goes by The La's, off their self-titled debut album. This is just pure & fluffy fun, and gods it sticks in your head FOREVER! A really great song by a really neglected group.
The next is Inner Universe, the theme from the Ghost In The Shell: Stand-Alone Complex, Season 1. It was composed by the *ridiculously* talented Yoko Kanno, and sung by Russian chanteuse Origa. It's a gloriously beautiful song, I just love it to pieces, plus that woman can SING!. You can find this and more great music on the GITS:SAC Season 1 Soundtrack.
That's all I can actually locate on my hard drive at the moment, too little sleep lately, but I'll try and be back with more!
