Back when iTunes came out, the keynote address, Steve said something that stuck with me. "You can take your purchased music and sync it to as many ipods as you want.. 10 macs... and burn the music 10 times.." --or something like that. Is there something saying that the music has to be purchased by you, and that the unlimited amount of ipods must be owned by you? Because, i have purchased allot of music i got from friend's iTunes. Played it awhile and decided i'd like it on my computer... and purchased the songs. Should i be buying the songs if i have them on my ipod? Just clarification, my friend wanted me to ask this for him.
