This is the weirdest thing I've ever heard.
At first I thought it was a simple mash-up album: take music from Super Smash Bros. and music from the Space Jam soundtrack and mash them up together. Turns out it's much simpler than that. And stranger. It took me a while to work out exactly what was going on. I was scrolling through each track to see which Nintendo music had been paired up with 'I Believe I Can Fly'. That's when I slowly started to realise that this wasn't a Smash Bros./Space Jam mash-up album. This was a mash-up between Smash Bros. and one goddamn song from the Space Jam album.
Here's what this album is: it takes that one weird Space Jam song -- only one -- and imposes that one song onto a number of familiar songs from the Super Smash Bros. soundtrack.
Weirdest of all -- it sort of works. "COME ON AND SLAM! WELCOME TO THE SLAM!"
Seriously, this is art.
