Yeah, even the default WM lock screen does cause a stop in playback in HTC Music the first time you use it, but the problem I have had (even with the stock VZW ROM) was a constant stop/start of playback every few seconds on all MP3 files. Looking in a task manager, you will see AudioManager_eng.exe spike the CPU at those times, it was having a hard time with something in my case.

I don't think HTC sets the process priority for AudioManager_eng.exe high enough, which is what I think causes the problem with lock screens and such. Maybe on something like the HD2 it's not such a problem?
