For film music, music director A.R.Rahman (oh and he won golden globe for best soundtrack for slumdog millionaire)is a safe bet. Some of his albums are very well recorded and mastered. If you can find the original disc, great, some of them are OOP and slightly hard to find.
Some of his notable releases for good songs and recording quality are Lagaan, Dil Se, Bombay, Taal (known to be his personal favourite since the movie itself was a musical), Yuva, Swades, Rangeela. You should be able to find these on amazon
Rhythm, Alai Payuthe, Kandukondein Kandukondein (these are south indian movies, Denon uses songs from the last one as their demo). Slightly harder to find the original discs, but easy to track down in mp3 format.
