Question about soundtracks, copyrights and ModDB !

[daortir]

Hello there ! I have a question regarding the use of soundtracks in my Custom Story. It is fairly simple : what am I allowed to use if I want to upload it to ModDB ?

I know I can use the full TDD/AMFP/Penumbra without any real issue, but then ?
Some mods have been deleted from ModDB for copyright issues but it was more about stolen models I think (Heart Bondage stealing Alice Madness Returns models like crazy)

Does anyone knows precisely what happens if I use music from other sources ? I know Dark Case did it and I am pretty sure there was no problem with ModDB.

Every mod we make here is free, so can we use anything we want when it comes to audio content ?

I am very noobish with copyrighted stuff, and I would love to beneficiate from more experienced modders.
