To transfer a lot of songs, you'll need a pro membership. ($20+) For that price I expected the transfer to be perfect. But unfortunately the vast majority of my songs made it over in weird versions that were either remixed, or on strange compilation albums by 'various artists', which made it such a pain to have a nice overview of all songs in your library. (Since they don't actually show up under the actual artist)
Please work on actually matching the song with the original version, on the actual album of the artist. Instead of these strange randomly generated generic compilation albums.
