Do you remember the song that plays in the background as Rainbow Dash battles Trixie in the episode Boast Busters? If not, go look it up because it's a great song!
Anyway, Power Chord made a new recording of the song that you can listen to over on Soundcloud. Power Chord actually made a version of this song a couple months back, but this one is new and improved. In fact, the quality is so good that it rivals that of the original!
Power Chord also has a Youtube Channel with lots of other great music. Thanks for sharing your musical talent, Power Chord! And don't forget that Top Hat made tabs of this song a while back so that you can play it yourself.
