OK, so I have attached the logfile. There is the raw file and one I edited to show only the relevant parts (I hope).
I went to browse artists and selected "The Monochrome Set". The box started playing "01 Inside Your Heart". This is the first track of the first album of which there are several for that artist. I then clicked next track a few times, but instead of selecting track 02, it repeated 01. I the let it play through to the end. Instead of playing 02, it then went to the next artist "The Noisettes". So the bug seems to be that it thinks there is only a single track for the artist "The Monochrome Set".
Next I browsed back to the other artist for which I have noticed the problem "The Dukes of Stratosphear". I only have a single album for this artist. It started to play the first track "01 25 O'Clock". Again I tried to change track a few times but it just restarted track 01. So next I changed to browse albums, but did not change it. Track 01 started, and then I changed track to "02 Bike Ride to the Moon" and then to "03 My Love Explodes". So it advances track in album play mode, but not artist mode. To prove this I then went back to browse artist and tried to change track 01 to 02, but again it failed.
I then browsed back to "The Monochrome Set" and switched to album mode ("Black And White Minstrels"). Now I could advance track 01 to "02 White Noise", "03 We Are Zarbie", "04 I Dont Know" and "05 FleshTrashHeat"
I didn't do any track advance for other artists, but the ones I have tried do work properly in both artist and album modes.
Thanks in advance.
