Since one of the last updates (I don't know exactly since which one, because the updates came shortly after each other. I currently have 3.8.36) my songs load much slower. I never saw the blue dots circling before, but now they always do.

Same problem with 3.8.37 on my both SurfacePro 4 tablets.

Please long press one of those songs, tap Share->Export as .msf and send it to mike@zubersoft.com. I'll take a look at it to see if I also encounter the slow loading. I'm using multithreading now to allow some of the work to be done on the background thread, but I'm doing some of the work at lower priority to ensure the UI doesn't get bogged down by a page loading (which is important when automatic scrolling as you don't want pages being rendered off screen to slow down the scroll or cause it to stutter). So I'll have to see if this is related in any way to what is happening on your device.
