Gaana is now narmalizing songs and quite good. Actually need to find songs with those detailing that would benefit from wav than 320kbps...very few i guess?!!Gaana/Wynk won't give you lossless music. They call 320kbps music as 'HD'. Also, even if you download any music in either of the apps, you can only enjoy the same till your subscription lasts.
I have purchased 'lossless' music from Saregama only to find out later that their .wav format music is actually upscaled MP3!
