I have two albums... Believe by Disturbed and Believe by 4-Strings. When I was working out to 4-Strings, Disturbed starting playing, and really confused me. Its easily repeatable, but whenever I select Play all of 4 Strings or their Album "Believe", the Disturbed CD also called "Believe" is thrown into the play list. Whats going on here? Is this something I did wrong in setting up the ID3 tags or this is a known error?
