I made a midi file of Pentatonix's cover of Radioactive to help me with the harmony. Didn't fill out most of the lead. I don't have the beatbox part as well.
The bass part is insane. Some chords are dissonant so it sounds flat.

Anyone up for an online collaboration? My voice is OK, doing Mitch's part (tenor).
