I have the opposite experience both with the interface and the recommendations. I look forward to my Discovery Weekly and often use the "Daily Mix" and "Radio from this track" features.
I usually pick off the songs I like from these recommendation-based features and then I go to listen to at least their album, while adding tracks to mood/subgenre-based playlists for other activities. I dedicate time out of most of my days to just listen to music while walking.
I don't remember ever seeing a bug on the android app. Which's a bit odd now that I think of it.
Really polar opposite experiences from both of us. It seems that they're catering to people with my usage patterns, however it may be that they differ from yours.
