My Issue

I'm sure you're all aware about the glitches when Dragging/Re-arranging the your Queue in mobile right ? it's been there for AGES. When you re arrange or drag a music on the top of your queue it will glitch and now you're queue is ruined and you won't be able to re-arrange it or even see the queue unless you close the app and relaunch it.
I hope you're all also aware your desktop app FREEZES most of the time for no reason. 🙂 Always have to close and re-launch it if i want to change a music album or playlist. 

Another thing, up till now why don't you have a feature to change our usernames/screen names ??  i don't see any reason why you're not allowing it. 

I always had this questions and issues for a long time now, co'z i thought you will fix/add it eventually, but i don't think that's happening anytime soon, so I just had the time to finally file a report/ticket. Thank You.
