Clearly, I am not the only pony obsessed with B.B.B.F.F! Seriously, this song is awesome—not that the other songs in the finale aren't—it's so adorable. I can't stop singing it.
Okay, enough gushing from me. The point is, we have chords for B.B.B.F.F. from eXT! The chords are excellent, and they would work well for guitar or piano (or ukulele, which is how I've been playing them). Take a look!
Thanks, eXT, for feeding my addiction to this song!
