Aha, I have found the problem LOL

I reset my Nokia N9. Transferred Maroon 5 album as seen on the video above. It took 30 minutes to fully sync album art LOL. Now it works fine and now it even shows up and no more black screen

I appreciate your help. However you should give this a try...

1. Download http://www.poikosoft.com/
2. Convert your music files to .M4A (Dolby Pulse HE ACC) 64KBit/s Stereo. Fill in your Tags etc, add album art.
3. Open MP3Tag and add the songs and then highlight all the tracks and just copy and paste album art and save.
4. Send to your N9.

The sound quality of the Dolby Pulse in 64Kbit/s Stereo is exatcly same as MP3/WMA at 320Kbit/s, give it a try
