[firmware suggestion] improved genre browsing + album artist browsing

So, what we need would be:

Artists -> play all, artist 1, artist 2… -> view all, album 1, album 2… (if you choose an artist) -> list of songs (if you choose an album)

Album artists-> play all, artist 1, artist 2… -> view all, album 1, album 2… (if you choose an artist) -> list of songs (if you choose an album)

Albums -> play all, album 1, album 2… -> list of songs

Genres -> genre 1, genre 2, … -> songs, albums, artists, album artists (once you’ve chosen a genre, you have the same display as the main menu, except only for the genre you have chosen)

Would that be difficult to implement??
