There are lots of complaints over the layout of the new UI for the Windows Desktop Application. A fix is to make the layout "barebones" and allow your community to make custom themes and layouts so each user can customize it to their liking.
The black theme physically pains people's eyes, causes migraines, and causes ghosting for those working on white-background applications. This is discussed in other ideas on this site. Even reading lyrics for 10 seconds causes pain when switching back to a white background application.
I've attached a simple inverted colors layout. Added some of that "Spotify Green" to certain parts to help them pop.
This idea has already been submitted here. Feel free to add Kudos and comment on it to show your support! It has been marked as not right now but Spotify might come back to it in the future.
