some songs not playing after mac

[schwin54]

I was at a friends house and tried to hook up my ipod to his mac, since then some songs on my ipod won't play. This is evene after i've updated it on my home pc, any solutions?

try removing the songs that wont play and reloading them if you can
i have this problem every now and then with my purchased music and i just simply have to remove them and put them back on
