Lots of loops are ripped from copyright audio which can result in a lot of problems for Blockland Glass. I think Blockland Glass doesn't want to deal with this problem which is understandable.

Probably just to be safe, I'm guessing, if some no-fun having douche (Viacom) decides to file a DMCA complaint it could get glass taken down for mostly just using pieces of music without permission. Copyright strikes have done b.s. like this before in the past, because like I said, just uploading/using somewhere makes you vulnerable for a DMCA takedown.
the songs are usually cropped and turned into mono OGG Vorbis loops
I sometimes wish certain companies would actually care more about copyright and stuff just to see 99% of GMod's Workshop Content just go poof.
Why would you want this to happen?
Have you ever seen the Gmod workshop?
