If you have never heard of the Gaana.com, it only means you are not in India. The service is one of three in that country, letting people worldwide stream free and licensed music in 21 different languages (thank you, Wikipedia). It competes with Saavn and Hungama with Saavn grabbing most of Bollywood's music catalog lately. Gaana now focuses on a lot of regional stuff, as a result.
Anyway, the developers behind the Windows Phone app have been going on a tear this last week, overhauling the app to bring it more in line with iOS and Android. This after nearly a year without an update, so yeah, a big deal.
