Karaoke songs

I've searched quite a lot for tamil karaoke songs on the net but really didn't find any site that hosted perfect minus one tracks.People always confuse karaoke with minus one tracks.A karaoke track is usually done using MIDI(though the track will be in mp3 format) which is sequenced by somebody and therefore will NOT be same as the original song.A minus one track is essentially the original soundtrack with the vocals removed(the vocal track alone is absent;hence the name minus one),so the beats and BGM are those used in the original song.These are hard to get,believe me.

Anyway some sites for karaokes and minus one tracks for tamil and hindi:

iniya-thamizhosai.blogspot.com
bdroot.com/karaokelovers/home/index.php
rose4you.dk
esnips.com

In esnips you'll find hundreds of tracks.Search appropriately.
