Comment 8 for bug 366091

This is assuming there would be a tiny preview player (e.g. above the
searchbox) with just a play/pause button and a mini-waveform just as wide
as the sidebar that you can seek through the track with. If you wanted to
embed play/pause buttons into the library table then that is a little more
complicated. These steps I described will get you drag-and-drop to a
preview player and also right-click context option for previewing.
