//// I stopped renewing for their services from 2008 since I lost interest in their services. Since then, I am receiving calls almost each day to renew. I am not sure whether I should renew or not. ////
If you like international
music, I think you should renew. The quality of their broadcast has remained same for the past many years. There is no need for any apprehension in that. The quality is better than FM (without any hiss noice or disturbance, as this is digital broadcast) and slightly lower than CD quality (as the kbps level is lower than CD). Generally speaking, International music is given in better quality (higher kbps) than Indian stations.
They still have franchisee arrangements with X radio (satellite radio based at US). Hence, the exclusive international music channels do give more recent and popular numbers.

//// I still prefer FTA FM stations to be better than Worldspace. ////
Worldspace is in a much higher quality level (quality of content) than FM stations. FM stations give you the latest popular numbers if you prefer local or Hindi filimy music. That is all. Worldspace is full recipie. Actually, there is no comparison. Both cater to completely different sphere.
It is actually surprising to see how little music is there in FM stations now-a-days and how much more talk / noice is there. In FM stations, I only listen to AIR and not anything else, ever. But, even here, I am sometimes surprised how little is music and how much is talk and talk only.
BTW, Worldspace has many talk channels, including an exclusive radio channels for comedy talk. Amazing.
