Display full song title in tooltip on hover

[thewindsofwinter]

I often listen to various orchestral works, sometimes necessitating putting movements in sequence. This is hard to verify when the titles are like:

String Symphony No. 12 in G Minor, MVN N 12, III: Allegro molto

because tbh I can't really tell from the start of the title whether it's II: Andante or III: Allegro. I propose a tooltip to be shown with the whole title on hover, which shouldn't be hard to achieve, and I'll be happy to put in a pull request in a few days to handle it.
