When browsing into a Rhapsody playlist on SN web and playing a song from the playlist, I'd expect the playlist to continue being played track by track from that point on.
That's the way SB3 behaves, depending on "Play Other Songs In Album" player setting.
However on SN web the single track is played in loop.

There should be a way to start playing a Rhapsody playlist from an arbitrary track within it via SN web.
