Dei Machaan Dev (Thumbs Up)
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!
