To whom it may concern:
Please please let me have more than 10,000 songs in my library. Last.fm says I’ve scrobbled 26,652 different ARTISTS since 2012. Many would agree that 10,000 isn’t really even very many songs. You can probably also make it easier to actually remove large amounts of items from the library if you want.
Sincerely,
Matt Thompson
