Is there a real reason?

Ok. i am almost 14. when i was like 9 the boyband dreamstreet came out and they were like famous until 03 i think. the band consisted of 5 boys. Jesse McCartney,Chris Trousdale,Greg Repaso,Frankie (don't know last name) and Matt Ballinger. I used to love the band and then they split up. Why is it that they don't sell there cd (It Happens Everytime) anymore. Is it because they split up? I mean they are still selling other old cd's like Styx,Dana,Air Supply all that stuff besides ebay does anyone know where i could get a cd... or why they dont sell it anymore?
