I don't know if it is the same problem you have but the tagging on my device is well off. It only recognises album artist over actual song artist. This means for example if I am listening to an album by Whitney Houston every single song will show on the device as Whitney Houston and never tells me the artists that feature on any of her songs.

However that is not where it gets fully annoying. The most annoying is when I am listening to a compilation album. The artist for each and every song will show as Various Artists so I can never tell the artist that sang any of the songs.

I will give a very huge present to anyone that can help me solve this problem other than me actually having to go back and incorrectly put the song artist in as the album artist for each song.
