KitRifty (who's shared his musical talents with the site before) is back with a great transcription of Becoming Popular. It's a faithful representation of the original and an all-around fun song.
Listen to the midi in the video, where it's been resynced with the episode. Then you can download the midi or a Musescore file for your own listening or remixing purposes. Becoming Popular is one of my favorite songs from this season, so I'm thrilled to see another excellent resource for it.
