I have used a big screen for years now, right now a 4K 50" with Ambilight which is great for a party feeling when I want that. I use Spotify daily and I have tested several third party apps but I really don't like any of them. Especially since I have to tab back and forth to change songs, see what is playing or what time a certain part of a song is, add songs, delete songs, see what artist is playing, and much more.
I have been a faithful premium subscriber for about 10 years now and this is the one thing I really would like to ask for in return.
The new desktop update looks amazing on a big screen and the last thing to complete it would really be a built in visualiser.
Please, please, PLEASE Spotify. Add this feature and make me and so many more fans happy. It would really change the experience for the better.
