Plug a microphone into your broadband-enabled computer and head on over to SingShot.com, where you can create, share, and listen to karaoke performances. Pick a song from a list of more than 2500 and start caterwauling away.

Free membership entitles you to enjoy the performances of others, rate them as good, bad or awful, and create a personal page complete with a 3D avatar. Actually recording your own karaoke masterpieces costs between $4.95 and $9.95 a month, after a free two-week trial period.
