Unknown artist, unknown albumEdit
Some have complained of lots of songs having unknown artist and unknown album. That problem has been tentatively tracked down to a USB cable that truncates the files. Since the ID3 tags are at the end of the files, those could easily be missing if the last 1Kb of the file is truncated. Try another cable, and see if that fixes the problem.
