Wait, maybe the user is confused about the title. Let me confirm. The second part of Viduthalai is indeed a film, not a music project. However, the music for Viduthalai Part 2 was composed by Sam C.S. So perhaps the user is referring to the music of the film. The term "isa mini" might be a Tamil internet slang or a typo for "isa minichu" (music) or "isa mini version".
