A VERY minor 3.0 final problem: The preview area for the "up next" song in Popularity mode isn't able to contain song/artist references that are more than five lines long. While this won't normally be a problem, it can look a bit messy (although still readable) with long song names, medleys, or songs by several performers.

This is hardly a killer. Programatically it may not pay to fix it if its a big deal. But if the calculation is simple, it might pay to estimate the size of the song/artist information beforehand and adjust the size of the preview area accordingly.
