I wish to share links to two websites that contain a plethora of songs
from regional films and albums, besides Bollywood music as well as
Carnatic and Hindustani recitals.

http://www.hummaa.com
I found a wealth of rare songs in Marathi and Bengali on this site,
that I had never heard before. For example sake, I had never heard
Lata's "Pankh have maj poladaache" (composer Meena Mangeshkar) before.
In Bengali, I got to hear Lata's "ek baar bidaay de maa..." sung for
Aparesh Lahiri. Beautiful composition! The site also contains songs in
Tamil, Telugu, Kannada, Malayalam, Assamese, Konkani, Bhojpuri,
Punjabi and Gujarati.
