Songza is popular mp3 search engine. Here you can search many mp3 songs and listen, like bollywood songs, hindi songs and many others , you can also create your songs playlist and save for next time or your other friends.
I like some more features of songza minimum ad, no popup, Embed in site.

Songza is nice, but MusicVistas.com is even simpler. And, you can build and store multiple playlists as well as access shared playlists.
