Itunes help

[!EpIc fAiL!]

so i downloaded 2 songs from itunes but i think they are corrupt because after i loaded them on my zune, my zune has been acting up( EX: wouldnt pause, skipped when i did various other things). so how can i re-download them to maybe not get a corrupt file (if thats possible)

first remove them from your zune see if it works or not, if it works fine then re down load them from itunes store if not then contact the people you bought your zune from (taking it that its within its warranty) and say its not working and get them to repair or replace it
