You know, there's much truth to this. If he bought the music, he bought the rights to listen to and use this music as a personal entity. Whatever your stance is on downloading, I'd think he'd have personal rights to each song provided he has the original cassette to prove he bought the 'album.'
On the other hand, go with what
CyranKrin said except your should always go into the line input instead of the mic input because of impedence matching. Plugging a tape player output to a computer mic input will be far too hot - although possible to do, not advised.
