I have mostly classical music on my device and Artistlink works tremendously well. I have spent quite a while catalogueing my music so that under artists it has the composer's name, the genre refers a specific musical genre, and the year is the original composition year. I cannot fault the results i get. I turned off the network function (whatever they are) and subsequently the artist link background service (both in preferences) after i found that some files i had ID'd were being changed. I have been particularly impressed with it link 4 or 5 quite underheard of comedy acts, i always assumed it was because i put them in a "comedy" genre, rather than any CDDB resource... Not sure if this helps anyone! H.
