Music Player is choppy when advancing to next song when screen is locked

[Rick Spencer]

Steps:
1. Choose an album from the music scope, preferably one with continuity between songs (Pros and Cons of Hitchhiking, for example)
2. Click play all
3. When the music app starts playing, lock the screen
4. wait until the song is over

Observed:
The music is choppy (breaks up) as it advance to the next song

Expected:
The music is smooth, even if there is a slight delay

I have heard this behaviour as well. I think it is probably due to a CPU spike when calculating the next track which is worse because of the high CPU usage of pulseaudio recently (bug 1335342). I also assume that this will be resolved once we move to using background playlists in media-hub as the next track will already be in a list and the music-app will be suspended.

FYI This is probably related to the track not advancing onto the next track correctly [0] [1]

I don't see the music breaking up at all under the same conditions as the mentioned related bugs. If we don't see this reappear as the others are fixed, I recommend we close this as a temporary side effect or unrelated issue.

Does this still occur? I believe that this has been fixed a while ago? I'm going to mark as incomplete until we have confirmation either way.
