muththukkaloa kangal thiththippadhoa kannam(In want of a better source of the lyrics. This will be duly updated if a kind soul provides one.)
sandhiththa vaelaiyil sindhikkavae illai
thandhuvittaen ennai
[...]
muththukkalae pengal thiththippadhae kannam
sandhiththa vaelaiyil sindhikkavae illai
thandhuvittaen ennai [Muthukkalo Kangal]
Endless loop, for more than a week now.
Update at 10:24 p.m.: An update note was added on updating the post with the lyrics of the song, but without an update note, a few minutes ago.
