I currently want to do something "big" for a Famitracker project (aside from making covers of other non-pony songs). Here's what's on my mind: A demented and twisted medley of Pinkie's songs from Season 1 to Season 2. Why do I need someone to collab with me? Because I plan on having this awesome wave battle near the middle of the track. That, and I'd like to be able to share melodies, background patterns, and chord progressions with this collaborator.
Hope you fellows can help soon enough!
