Slipknot – Mate.Feed.Kill.Repeat Album Lyrics

i was wondering, if my copy of this album was a re issue ( it has 16 songs instead of 8) what does it matter? whether it is real or fake? it sounds like slipknot. also the different direction the previous singer was trying to go in. is it just to say, i have a original and not a reprint or re issue? if that's the case all my cds are reissues
