Why are some Playlists empty, or contain discrepancies or errors?
For mp3/ogg/aac+ streams, we capture what the stations broadcast. It’s a free world, and stations have no obligation to guarantee playlists are perfect. However, it is in the stations best interests to display accurate track info, so errors tend to be the exception and not the rule. For all other streams (e.g. WMA, Real, Flash, Quicktime, Silverlight, etc.) we do not capture track data.
