Why was ACZ2's music changed?

I prefered the original one, with no lead, but either's fine. So, why was it changed anyway?

ACZ2's music wasn't changed, since ACZ2 doesn't exist in a complete form yet. Tunes 14 probably won't end up being the track used when the map's complete, and my proof is that Nev3r told me not to use it 'cus it's not great. The final track will likely be either modified further or swapped out with BW's remix or something like that.

If you're wanting to use the leadless ACZ2 track in a level, it's somewhere in the 80s of musicslots.
