Wow, I was going to say I assume the pic in the top right is of the official Spotify client, which seems confusing, but it seems this actually just looks really like the official client. Which is good but possibly makes it more likely Spotify will come after you.

The UI feels a lot less sluggish than the official client (which in my experience seems to have gotten way worse lately) but in many cases I am just sent to a loading page which ultimately takes a similar amount of time to load the content. So it seems a lot of the slowness is coming from the Spotify server side, it's just that the official client seems to freeze while waiting for a response whereas this doesn't.

Hopefully Spotify don't kill librespot. As I understand it you can basically only use it with Premium accounts, so it's not like they aren't getting paid anyway. If some other provider were to come along and offer access to the same content as Spotify with a stable API that you can use with any client, I would pay more for that than I currently do for Spotify.

As an aside, ncspot is another good and more minimalise Spotify client, which is a TUI.
