Why on earth did someone think "Swiping left or right or right between songs and artists is too easy, let's have them tap a small button in the top left, then tap 'My Music', then tap a category. That would certainly be better."
It's absurd that a UI would get "updated" to make things harder to accomplish. In addition, people have been asking for imported songs to be included under the 'Artists' and 'Songs' lists for months and months now, and instead we get this awful UI regression. (How hard can that it be? It's probably like five lines of code.)
