mp3+g

via waxy:

a usenet group devoted to swapping karaoke versions of popular songs is unusually popular, with 7500+ songs posted in the last month alone. i don't know where the original files are coming from, but the diversity and timeliness of available files in alt.binaries.sounds.karaoke is staggering.
...
some of the more oddball gems were karaoke versions of king missile's "detachable penis," nirvana's "you know you're right," electric 6's "high voltage," liz phair's "fuck and run," pj harvey's "one line," and the dead kennedys' "too drunk to fuck."

pardon me while i frantically dig for a usenet account.
