Just downloaded it, and brought up a list of artists, and it split them up and categorized them quite strangely. For example, I have 4 Dashboard Confessional albums on my phone, and it listed one album as "Dashboard Confessional" as the artist, "Chris Carrabba" (the frontman of the band) as the artist for another, "Christopher Carrabba" for one, and "Christopher Ender Carrabba" for the final album.
Not the end of the world, but it makes the list of artists much longer than it needs to be, and could be confusing to some.
It also did that for a few other albums, where it used what I assume is one of the band members' names in place of the band's name.
I'll keep it since I got the free d/l, and it sounds like it won't be free forever, so maybe updates will clear up this issue.
