Hmm - I haven't really noticed any unresponsive-ness but I also am a paid subscriber, I wonder if the ads are responsible for the slowness?

The spotify mobile app has some odd behavior from time to time. The UI will continue to respond to my actions but nothing actually happens for 20 seconds, during that time i'll click on several different songs attempting to get them to play.

Finally, for whatever reason, the app springs back to life an begins to execute the actions out of some sort of queue leading to several songs playing. It seemed very odd to queue song plays in such manner. I would've assumed it would be last one wins rather than "Song 1" - play for 2 seconds "Song 2" - Play for 2 seconds "Song 3" - play for 2 seconds

I may have clicked "Play song 2" 15 seconds ago before the song is actually played.

Overall, I love spotify though. I use it everywhere.

Spotify and SoundCloud are testaments to how users will endure whatever awful UX you give them as long as they're getting enough value from your thing.

The soundcloud mobile app is not that bad, at least on Android. It has the best audio scrubbing of any app I've used. The UI is super simple and made to work at a distance, e.g. while mounted in a card holder.

I absolutely hate the soundcloud app compared to the spotify app. Constant crashing, locks my phone up, random pauses during playback. Android, Samsung Galaxy S4. The UI is fine I just wish it didn't break every other song.

I'm also a paid subscriber and for me the newest version is clearly slower than the previous one, both on Windows & Mac.

Luckily there is a way to downgrade to the earlier version: http://www.reddit.com/r/spotify/comments/2y239w/a_guide_to_d... (The second method works for me)

Speaking of the mobile app, the lockscreen UI on Android is absolutely infuriating while driving... The "Skip Song" and "Close" buttons are right next to each other and far too small. Between that and the features they've been gutting from the desktop app I've gone back to Google Play Music now.

I've frequently been unable to pause or change the volume of the music for tens of seconds because the user interface stalled. Completely inexcusable for an app that is ostensibly for playing music.

On the good side, since all the webviews are right there in the app as renamed zip files, I suppose they could easily be edited to cut out some of the bottlenecks?

Uses >400mb of RAM for me and constantly uses about 5-10% disk usage.

It may very well be the ads responsible for at least a memory leak in my case.
