Odd iPhone issue.

[sifuhall]

Has anyone else noticed that occasionally the tags on the songs on my iPhone just aren't correct?

Today while I work I noticed that the banana boat song from Harry Belfonte was somehow in my Hair Metal genre. This is obviously incorrect so when I get home I check my library on Media Monkey and it is in the genre folk (which is where I want it). I changed it to something different and changed it back in hopes this would cause it to be updated on my next sync but after syncing it is still incorrect on my iPhone.

I'm have the same issue with a handful of songs and unsure what to do.
