I’d get a single stutter seconds into playback of a new song fairly often when playing lossless on Apple Music on my iPhone, without Bluetooth.

I suspect that the stutter happens when it decides to change audio tracks to a higher bit rate stream, but that’s me talking out of my rear.

That particular problem went away once I turned off lossless in Apple Music settings.

Same here. The stutter is quite annoying, and easily reproducible. It only happens when streaming lossless music; does not happen when playing downloaded music.

Amazon Music Unlimited has no stutter whatsoever when streaming lossless files. Perhaps Apple wasn't quite ready to offer Lossless, knew the stutter was there, and released it anyway.
