LimeWire does not provide any songs or movies or files to download. What you find on the Gnutella network are what people like yourself share. So if anybody is sharing what you are looking for, then hopefully you can download it. And hopefully share it & other files back.
I'd experiment with your search techniques & search criteria to find what you are looking for. I don't know whether they'd be named in in hindi or english language. Try searching something very popular. Also, check the other threads & posts in this section, some people have put together some good tips for finding karaoke files.
