Music Player

Sure looks fine, I think a narrative is always somewhat implicit in side by side screens so a small improvement would be to add Dua lipa's track to the middle screen as the implied journey starts with Viva la vida but jumps to sharing a Dua Lipa track when due lipa didn't appear on the middle screen.  

• The middle screen is called 'Music player' but I think it's actually depicting a Library, catalogue or exploration area. Might be best to rename it's title.
• For the time controls on the player I'd prefer if the bobble for the time slider were the same colour as the rest of the bar
• Those white controls on a glassy background feel a bit hard to decipher in the example you have shared! I think they would be better to be constantly blocked as a sticky control at the bottom
• 'Recently listened' feels grammatically weird I'd prefer "Recent listening"
