Since latest valve quick patch or whatever a few days ago, all music on tf2 servers where we are allowed to play music gets sped up and squeaky (sample rate is shot way up for some reason). I'm pretty sure plugin broke or something. Here's a demo where i'm playing Bohemian Rhapsody on the mariokart server to show what I mean. This same exact music file with the same software (Slam/HLDJ) was working fine a few days ago.

Paste the file into your tf folder in tf2 directory than google how to launch demos if you don't know.
