v2.0

Following up suggestion from BKK to have music accompany each cover, I am attaching a Work In Progress V2.0 build. Thanks again to sverx for sending link to Maxim's pcmenc utility and huge thanks goes to kusfo for helping trouble shoot all issues during development!

The one thing I did notice is that when the converted WAV plays on cover art load, the demo does block until riff completes playing i.e. no input is detected or pause button etc. I'm not sure if anything can be done here with this but somebody pls correct me if I'm wrong... thanks!
