Tata sky does not have enough music channel in its baggage. Just MTV & VTV and zoom if you upgrade to lifestyle gold.
Music india, 9XM, B4U Music are not in tata sky package.
No sports channel in base pack i.e. super saver or family pack, except DD sports. They charge Rs 40 to 65 per month for viewing sports.
I think bigtv is a good option for covering all these channels in their premium pack, and that too at a lower cost. Also there is no warranty at tatasky. If they come to attend a complaint at ur home after a month of installation, they will charge Rs 300 if the fault is because of u, which they always prove.
Tata sky is best loved by those, who want to see saas bahu serials only. Their channel package is full of all such channels. But alas nowadays their is strike in these serials also, on the payment demands of actors and producers. So now the tatasky is worth nothing. Just listen the news and shut off the tv.
