I think the music + videos live tile has got to be my favorite of the lot now, thanks to MPAtool.
For those without Xbox Music accounts, MPAtool is a great app that lets you append pictures to your artists.
It does so by creating a dummy file with the image. Somehow the music + videos app picks up the image, so even after you delete the dummy file, the image remains for the rest of the artist’s songs. So you get that glorious picture of your artist instead of the dreary grey that music + videos defaults to if no images are detected.
Its not as pretty as the changing pictures of Xbox music, but I’ll take what I can get!
