iPod Cannot get music onto ipod?

[fifth gen]

Hey guys

I did search for this but didn't seem to find exactly what the problem is.

First off, im typing on my new MBP I officially jumped ship haha. Anyway, I just transfered all my music from my pc to my mac via CD. Then I reformatted my ipod for my mac and transfered my music onto it. Unfortunately, it choose 100 songs that couldnt be transfered from my mac to my ipod. I have no idea why as they are all songs that were purchased on itunes. Anyone have any idea why this is or what I can do?

Thank you

It sounds like you haven't authorised your new computer. Play one of the songs in iTunes itself and it'll walk you through it.

Awesome thanks!

I didnt even think of that because other songs transfered.

Thanks again.
