I love the new interface, but one thing that kind of bugs me is the fact that the song, album, and artist sections of "my music" are all connected. If I like one song by an artist I don't want them to show up in my artist's section.
I think you should be able to add music to the sections independantly. So for example if there is an artist I really like I can just go to the top of the artist page and save them to my artists section, then I can choose there best album and add it to my albums section, then add a my favorite song to the songs section.
Just a thought
Right now I have no use for the artists and albums sections because they are full of artist and albums that only have one or two songs saved to my music.
