* Infinite scroll is broken in the desktop browser. I can't access songs in my library beyond the letter A. Why infinite scroll is needed here or anywhere for that matter is an entire discussion unto itself.
* Random music I've purchased is unavailable for streaming and has been reassigned to "shuffle with other songs" as I don't subscribe to unlimited. I can still download the songs and listen to them locally however. To put it another way, some stuff I've purchased looks like I haven't, perhaps in an attempt to get me to repurchase it.
* Accessing a 30 second sample of a song is hidden behind a mess of dark patterns. Scrolling in this UI is broken as well with overlapping layers hiding text and graphics. In fact the whole purchasing of music has been deliberately obfuscated likely to encourage streaming.
* Searching for music within your own library is nearly impossible.
I could go on and on about this but my experiences have been so bad I'm left speechless as to how this made it to production. As a highly experienced technical user I can't help but feel how the average consumer forced to interact with this garbage feels.
