The Knife, Yeezy, and Trillville

The Knife is a rock duo hailing from Sweden. They dropped "Heartbeats" in 2004. The Hood Internet, a duo that mashes up hip-hop tracks, mixed Trillville's "Some Cut" with "Heartbeats". The result is insane. The makers of the Sky High mixtape followed suit, mixing "Heartbeats" with "Get 'Em High". The result is just as good, if not better. The original "Heartbeats" is copyrighted, so I can only give you the Youtube link. The other two tracks will be posted as Zshare files. That means download them.
