Help making first mod?

[TheCreeperDemon]

I am going to attempt to make a mod that replaces music in SRB2. Could I have some help if possible? (I completely understand if this gets taken down.)

Do you know what I did wrong? At some point it will start acting a bit weird.

Music replace is only for Act 1 of GFZ

Stay in GFZ Act 1 for around two minutes. It will sound weird by then. Don't know what happened.

All sounds well to me. The audio file is sampled at the right frequency and it replaces the existing music lump correctly. Other than the oddly-placed looppoint near the end, everything seems fine.
