SINGAPORE - You know that annoying tune that you can't place or get out of your head?

A U.S. company has recently launched a Web site, www.midomi.com, that names most tunes that you can hum, sing or whistle a tune into your computer microphone.

The Web site relies on voice-activated search technology that analyses sounds and matches them against a music database.

Based on the tune users ask it to search, Midomi.com also suggests links to songs that it thinks might appeal to the user.

"With midomi.com, we have created one of the most entertaining search engines on the Web," Keyvan Mohajer, CEO of Melodis Corporation said in a press release this week.

Users can create their own profile, sing their favourite songs, share them and get discovered by other users. Move over American Idol?
