I hate myself for yet again having a comment/request for the expanded panel, but I just can't be helped.
With most popular music and it's titles, the width for the columns is very good.
But for a lot of classical music with long titles, you often miss the last part of those titles, which makes it sometimes impossible to distinguish between tracks.
I myself can imagine two possible solutions for this.
Either have the column widths adapting to long titles, or have a second line for long titles.
(or maybe even a bit of both)
