Troubleshooting Zune Software?

[WhatWhat?]

I was downloading 2 of my mix CD's , one is White stripes, and the other is AC/DC, and somehow my zune software accosiated both of them under the same artist as two albums.I called titled the artist AC/DC, and tried to get my white stripes music to separate into another artist.And now, even if i delete one album and re- rip it, the zune software automatically associates it with AC/DC. I even changed the properties of all my white stripes music files to say that the artist isWhite Stripes, and it still puts it under AC/DC. I've moved the white striped music into another folder, re titled it, and still nothing. Is There any way to seperate the two albums from the one artist, to two artists? Because having to find AC/DC to play my white stripes music pisses me off severely.
