Sorry, first post here, so if this has been asked before I can't find it! Have only just downloaded Mp3Tag 
I have just bought a SqueezeBox 3 and have been transferring music but it didn't show Various Artists albums very well. It was suggested that I remove the TPE2 tag and SqueezeCentre would then treat this as a compilation album. This worked fine on the SqueezeBox but screwed up how the album was then listed in Windows Media Player 11, it now list each track under each track artist.
It was then suggested that I could put the TPE2 tag back as it was and add a COMPILATION=1 tag. This is where I'm having a problem. I can find the iTunes compilation tag, so I changed this, but it did not help. Is there another way to add a COMPILATION tag that is not iTunes based and would work with Windows Media Player and SqueezeCentre 7.x
Thanks in advance
