On two separate SB Radios, (one with wired ethernet, one with wireless, both with 7.5 firmware) playing Rhapsody stations has become very undependable.

On previous firmware version Rhapsody stations would play for hours at a time.  After the firmware upgrade, Rhapsody stations stop playing and the device returns to displaying the clock in as little as 5 minutes and always in less than an hour. 

To reproduce this problem, use a SB Radio, with Rhapsody app installed, log into a valid Rhapsody account and play a station.  Note that other features of the Rhapsody app such as playing a playlist seem unaffected.
