Update "Genre" only from web

Hi all,

I took a lot of time updating all the fields in my mp3 collection.

I would like to update the "Genre" tag of all these mp3 using an online tag source without touching any of the other tags.

Ideally, it should use the correct genre for the song (not the album).

Any idea?



PS : I did search Google and the forums and the best I could find was this post, which is close but not exactly what I want (file specific instead of album specific)
