This seems like a pretty niche idea, but hear me out. I have two backing tracks for two MLP songs: Fluttershy's Montage (Which you'll find here) and Cutie Mark Crusaders (Which is here). Feel free to use these for personal practice of if you want to showcase your mad soloing skills at a talent show.
I plan on making more and will put them on the site when I make them, but until then, these will be here waiting for another rock god to take the stage. Rock on, bronies!
