If you set the Art & Details to Selected tab I've in the past been able to just slowly cursor down through a list to get this done.

There is no build in method to play just a small bit, not sure if there is an Addon that can do it.

Is there a way to have MM auto play songs for 10 seconds to generate lyrics and album art?

Would be great to go through all my songs vs opening, waiting for lyrics and album art, etc.... then next.

Thanks!
