Awesome program, the only thing I would add is a tab that sorts by song title, helpful if you have a ton of songs and you don't always know the artists.

I made a post that touches this issue.

This would, however, require some knowledge on the artist or the genre of the song you are looking for.

Personally, I just use the search field if i know the song name, or even just parts of it, but not the artist.
