Quite likely...

The ID3 tag is a small amount of data tacked onto the end of the file. Software like emplode and winamp can look at this and give you the Artist, Title, Album, Year and a small comment..

ID3-2 goes at the front of the file, and contains much the same, but without any limit on name length (and it's extendable, so could hold stuff like lyrics, relative volume etc)

I use MusicMatch 5 and it titles them with both ID3-1 and ID3-2 tags...
Best bet is to search for id3 in the RealJukebox help... =)
