Ok, I've been doing a little bit more testing and I've noticed there's a memory issue (has to do with how memory stream work.)  Thought I'd sorted it out already but it still seems to slowly eat up RAM.  Not a big deal if you don't let the music run for too long.  Until the bug is addressed I'd recommend not to let PlayChain play for more than 30 minutes, before restarting it.

Will post an update as soon as I sort it out.
