Jaex, not really suited for the collab, but I listened to their other works, and well, they've earned a new fan. Thanks for showing us that page.
Gatling's right: Let's Eat Spleen was perfect. It was weird, not serious, but not too light-hearted. I don't like Gatling's alternative song, though. Too creepy and slow.

It's from the same author that wrote 'Let's Eat Spleen'. I'd recommend this as an alternative, but Let's Eat Spleen is unbeatable.
