Sorry for the late reply, im currently gonna try to help you out. Anything, for free. No need to pay me :)
I REALLY APPRECIATE YOUR KINDNESS, The only problem is.. i just quit the app recently. I will get back once they actually made a good change for max2d
AND I mean anything. Even if not from Max2D (only music and some sounds tho)
Yoo honestly.... I kinda need some music for my unfinished projects. I'll let you know dude!
