Where can you get keyboard notes for new Tamil songs online?
try keylessonline.com that website is good because you can ask for songs you like!!! but the creator of the website is'nt adding new songs! but it's awsome!!!! they still have very new songs and hits of the decade!!! You can also go to http://kittu-mama-solraan.blogspot.com It has keyboard notes and lots of original karaoke tracks for free too.
If your looking for chords I can't help. but.. if your maybe looking for a book then.. www.musicroom.com books with notes, and chords. at different stages of piano, keyboard and guitar. And you can play most piano books on a keyboard, well I do. With and without the bassline, replaced with chords. There may be a Hannah Montana Music Book. But search around google.
