I voted the first one. I have a quite large music library (over one terabyte and about 100,000 tracks) and that video would have been the most useful to me.
On Windows, I used Winamp, which really is the gold standard for this application. But WINE does my head in, so I had to switch. I tried literally every single Linux music player out there and fooyin was the only one up to snuff. Everything else was too clunky to be usable with a library of this size.
