Free iTunes songs won't play on iPod

I want to know how many people have iPods and iTunes, and how many people have actially bought music from iTunes.

No, I’m not the RIAA, so don’t worry :cop:

I have a few free songs from the Pepsi iTunes giveaway, and I tried to put them on my rommate’s iPod (cause he asked me to download a song for him with his code), and the songs wouldn’t transfer.

:huh:

Is this just something they did with the freely downloaded Pepsi songs? I wanna know! :m:
