lol, drummers always talk shit about their bands ;)

I don't mean to sound patronizing, but you can plug in the headphones from the cassette recorder into your computer's line-in and record a wave file, then encode it. But, you need the right cable (microcassettes often have the ridiculously small headphone jack), and the tape deck has to have a headphone/output jack in the first place. Or you could hold it up to your computer's microphone :)
