Is this happened with you, that when you are travelling and some song comes to your mind, but unfortunately you do not find that song in your SD card? You may get it in Youtube, but as video will be played simultaneously it would be slow as well as it will eat up lots of your MB.
A few days ago I was in the similar situation. I Googled one song and got its link also but that was a streaming link which uses adobe flash player for streaming. I searched for many websites and apps and finally I found this piece of gem called Saavn.
Saavn music is a web application which lets you search and play any of the Bollywood/Tollywood songs. They recently released App for Android and Apple Platform and thus life became easier of songomaniacs like me.
But recently one of my Friend Smit Popat contacted Saavn developer team regarding Symbian release of saavn music application. And guess what, they are developing one for Symbian and Blackberry Platforms.
