Sorry if this has already been posted.. I looked through several pages and couldn't find anything on it.
Anyway, I have this issue where if I leave the player sit too long, or if my computer goes to sleep, when I come back and hit play it zooms through the playlist like it can't find any of the files. Closing and opening the app fixes this.

btw, love the app.. hearkens back to the early winamp days, before they tried to throw everything under the sun into the player
