well, it may just be me... but whenever I heard a song on a show, the radio or whatever, I would attempt to find it... that's how I ended up with a lot of cassette tapes... and before that records... now I have lots of CDs and MP3s (and M4As)

of course since google has existed, that's been a lot easier than say calling radio stations, asking around school/work... yup. now a days, a few lyrics into google = song found. Pump it Up is terrible... sorry.
