A user has reported an issue synchronizing multiple players while playing Rhapsody. Sync works fine for his own music. He has tested synching while playing Rhapsody from both SC and SN with the same results. He has tried this test while all three players are connected to the router using ethernet.

Here is his description of the issue.

First, the problem is not specific to SqueezeNetwork.  I encounter similar problems when using SqueezeCenter.  There are problems anytime I try to synchronize devices while using Rhapsody.  I've had no problems with synchronization when playing from my locally stored music library, even after 20-30 hours of music.   

Here are some details on the problem when connected to SqueezeCenter.  My setup is:

SqueezeBox #1: Duet
SqueezeBox #2: Classic
SqueezeBox #3: Duet

All three SqueezeBoxes were synchronized, connected to SqueezeCenter.  While playing a Rhapsody playlist, SqueezeBox #1 stopped playing, while SqueezeBox #2 kept playing until end of the song.  The light on SqueezeBox #1 stayed bright white.  I don't know if SqueezeBox #3 kept playing during this song.  At the end of the song, none of the SqueezeBoxes were playing.  The Duet #1 Controller showed the current song, with the timer counting from 0 to 30 seconds in a loop.  SqueezeCenter showed the same thing, 
except that the timer counted from 0 to 4 seconds.  After pressing play a couple times on SqueezeBox #1, all players resumed playing.
