connect olangal, nirakshana, autoraja, kannae kalimanae, ek aur prem kahani, paa.

Listen to the following songs

thumbi vaa - olangal (malayalam)
Aakasham enatidho from Nirakshana (telegu)
Sangathil paadatha kavithai - auto raja(tamil)
Neerveezhchi thee mootuthae - kannae kalaimanae (tamil)
Monday tho - ek aur prem kahani (Hindi)
Gum summ summ - Paa (Hindi)

all of them use the same tune but different lyrics. Whoever complained about ARR recycling tunes?

One of the songs composed by ilayaraja for a private album is being used in bala's "Naan Kadavul". Which one?

Pichchai paathiram Yendhi vandhaen from the album 'Raajavin ramana maalai'. A soulful melody. Hope the song gets its due credit, thanks to its screen appearance.
