Agua de Annique, Hey Okay! If Devin Townsend made pop, this is what it sounds like. It is simply too catchy.
Skullcrusher Mountain - Jonathan Coulton. Great for the line 'Isn't it enough to know that I ruined a pony making a gift for you?'
"Safe from Harm (Perfecto Remix)" by Massive Attack, also featured on the soundtrack for the film The Insider. There's some fabulous music on that soundtrack, but this could be the best. Listen to it.
Actually, this was the first Massive Attack song I'd ever heard, and I'd just heard it today because I have just finished watching The Insider, which the song was featured in. It's really great material though, and I'm panning through the YouTube collection right now.
Oh okay, I've been a fan for a while. I really enjoy Teardrop and Live With Me. It's way chill music, but it makes for great night or study music.
I'm not a big fan of the Rolling Stones, actually, but VNV Nation (an electro band) does a really great cover of that song. "It's No Good" by Depeche Mode.
