It would be useful if the artist that you follow would be visible under 'Your music->Artists'.
Now, in Your Music you can save individual songs o complete albums. In both cases, those artists that have recorded those songs appear under 'Artists' tab. You can 'Follow' Artists too, but those artist that you follow don't appear under 'Your Music->Artist' tab. And, if you go to 'Follow' tab you find altogether friends, artists, music magazines... A complete mess.
I love a lot of different Artist, and I don't want to save just an album or individual song. This way, I can seek in my artist to choose what I would like to listen. Just a list of your favorite artists.
