I wonder if it's struggling with the size of some of my playlists. I've got a 70 hour coding music playlist, that's the only thing I can think would slow it down during startup. My machine has 16GB RAM.
Helpful to know I might be an isolated case, though.
Hmm, 70H and downloaded? Because I have a 63H playlist in my 'Playlists' that I didn't make but have, and I have no lag like you describe on my Windows 10 machine.
The 70hrs isn't downloaded on my Mac desktop, just streaming. I've timed Spotify ("native" Mac app) at 25 seconds from launch to UI - but even at that point, the Browse UI still doesn't appear for a long time.
Guess I'm just unlucky on this one. Thanks for the additional info though.
Works great for me. I could understand not liking it if it did that on my machine though.
