One thing I do on the HD300 is start a random music playback then start a random slideshow. On the SHIELD when the music track changes, the slideshow stops like I pressed the left arrow, (back on the home menu screen with the selector on Photos > Random Slideshow).
In the latest version the client no longer plays more than one song in a playlist. Tested on SHIELD tablet with Gemstone and stock UI. No issues with the HD300.
