I ask you, what’s more frustrating than falling in love with a tune that drifts across your radio just once? I knew, for example, that I really liked the song from Fox’s Party of Five; I could hum it, but could I trace it? The solution came when I lucked upon The International Lyrics Server (www.lyrics.ch), a site invented last February by musician Pascal de Vries, who lives in Switzerland, and three friends. ”We were performing covers of rock tunes from the ’60s and ’70s,” says De Vries, ”and there was no single, accurate source for the words.” By typing in a few words from the song (”Everybody wants to live like they wanna live”) I got my answer (”Closer to Free,” by the BoDeans) in about three seconds. More than 65,000 songs can be tracked down in the site’s archive, which concentrates on rock and pop tunes but also provides an expanding library of rap, country, folk, jazz, and other genres. There’s just one problem: Publishing lyrics online is legally iffy — and who knows how long the site will be around. But for now, operating Lyrics Server from Europe puts the boys in the band beyond the reach of American lawyers.
