Here is the music review/analysis of Karthi's Dev, directed by Rajath Ravishankar. The music is composed by Harris Jayaraj.

Dei Machaan Dev (Thumbs Up)

Dei Machaan Dev is the typical Harris Jayaraj track that you find in every album of his... in a good way. That is, the track has his signature all over it. Be it the gibberish lyrics at the start of a song, to the pulsating beats in the background, this has everything. The term 'Dei Machaan Dev' is a catchphrase that hooks you. Coupled with Vivek's trendy lyrics, this is a sure-shot hit number!
