I hope that you will find Hubski to your liking. To direct you a bit, I can recommend bfv's weekly thread on music, here is the most recent entry. Quite a few people around here enjoy or play music.
To figure Hubski out, I would encourage reading FAQ and going through the tutorial (at the bottom of the page you'll find a link to it, along with other useful links). Sorry if that would seem patronising, but many newcomers ask questions that are answered there already and it can prompt some people to annoyed and less-then-helpful remarks. ;)
Cultures-wise, it's pretty dispersed. The majority of people seem to be from the USA, Canada and various countries from EU and beyond. I don't think that I recall anyone here from India, but I'm here from only around April.
