You Can listen online radio (Hindi songs). But what happens is every time you need to open a browser and Do several clicks in order to tune into a radio station. I will tell u simple steps (For Windows user with internet) which is really good.
1. Download and install iTunes download itunes
2. Open in any browser shoutcast.com
3. In "Search For", Search for Hindi. You will see around 40 Radio stations around the world playing Hindi Songs 24/7
4. Open iTunes
5. Now click on 1st link in shoutcast result. The link will open in iTunes and will be kept there always even if u close the itunes.
6. Then click on second "Tune In", This site will also get loaded in iTunes. Similarly repeat the same for all radio sites in shoutcast.
7. Now from next time onwards, No need to open any browser. Just open iTunes and listen radio. If good song is not coming in one radio, just double click other radio station.
