As coincidence would have it, v 1.4.6 was just released. I installed it, but the bugs persist.
If I go to songs, some selections are greyed out with a cloud icon and the message: “Item is on iTunes Match.” Don’t know what that means but I have tried turning off iTunes Match without success. I can’t play these songs unless I add them to a playlist through iTunes.
Also, if I choose Artists and them select one, the app will crash. This only happens when selecting certain artists, others will open fine.
Under “What’s New” it states “Fixes reported issues” but doesn’t mention anything specific so I am at a loss.
