It's an XL level, the song is used until 3:44. While I'd like for there to be a part around every 15-20 seconds including transition time, no way in heck that's happening. I think around every 30 seconds will probably be best. We'll also build parts in order on the same level base so people can go wild with 2.2 rotates. Also if you think you need it feel free to use song triggers to resync.
