Years ago, this fella named Hellbound Dochi made a double-set of two CDs of a spectacular mash-up of Eminem's vocal tracks and some of the best music in anime. The final result was the Eminem Anime Albums. And unlike a lot of mashup 'artists' who just match the BPM of a vocal track over an anime karaoke track, this guy went ahead and MADE most of the background beats. It's artistic, it's amazing, and oddly enough, it's pretty hard to find these days. My only problem is that he switches between using the clean and dirty versions of Eminem's songs, and that can be a bit jarring.
If anyone can find it, please share it with the world. So far, I can only find one link, and you need to be a member of that site to download it, apparently. I wouldn't know, I downloaded it back when he had a Mediafire account.
If nothing else, every track is on his Youtube account.
Eminem Anime Albums. It's a work of art.
