1) mine works fine 2) it does that... if it's charging, it's on. You might think of it as a "feature" 3) You're right, it does not recognize album artist as tag, only artist... which means that for albums with multiple artists, you're SOL, or you need to retag the albums differently, unfortunately. Player could be improved, that way. Edited to correct #3 above: my bad, ZX300 does manage album artist correctly. One needs to make sure that the proper setting is selected in playback settings (sort by album artist) AND make sure that the songs are properly tagged with the appropriate album artist tag... if there's no album artist tag (=if it's blank), player processes the ARTIST tag, instead.
