I was at my friends house and put some of her songs onto my flash drive from her itunes. When i try to put them on my itunes it says that I need to authorize it using her acount. Is there anyway i can bypass this?
No. This is something used by Apple to regulate the flow of mp3's between computers. I think on one account or iPod, etc., there is only allowed like either 3 or 5 authorizations.
