Krazzy 4 produced by Rakesh Roshan marks the debut of his assistant Jaideep Sen and stars Irrfan Khan, Arshad Warsi, Rajpad Yadav and Suresh Menon in the titular role along with Juhi Chawla  and Dia Mirza. Shah Rukh Khan, Hrithik Roshan and Rakhi Sawant each with an item number to their credit

Rajesh Roshan who has given some pleasing songs in the past right from the Kaala Patthar and Mr Natwarlal days has helmed the music of this comic flick. There is no doubt that the two item songs, Krazzy 4 and Dekhta Hai Tu Kya will be on the top of the charts. Dekhta Hai Tu Kya with lyrics by Javed Akhtar has been rendered by Sunidhi Chauhan and Kirti Sagathia. This follows the tradition of the legendary Beedi Jaleyle number but has a folk feel to it.

The title track has been composed by Asif Ali Beg and sung by Vishal Dadlani of Vishal-Shekhar fame. This number has one of the best contemporary lyrics, music that makes us tap our feet and a colorful rendition. In its second remixed version in the album, courtesy DJ Aqeel, the number retains its flavor and is as catchy as they come.

Break Free is the third song in this album and is as good as the other version of the title track Krazzy 4. There is just some slight change in the lyrics here but it more or less, sounds the same. The lyricist Asif and singer Vishal remain the same as well. The attitude of the song is extremely infectious and one gets carried away by the beat.

Roshan who has given us only the expected contemporary music to his fans has taken his fans by surprise with the next two numbers on the album, O Re Lakad and Ik Rupaiya. He seems to move into an entirely different zone and these two songs take us back to the Eighties and Seventies. The first of these two, O Re Lakad has been written by Javed Akhtar and sung by Kailash Kher, Neeraj Shridhar and Sowmya Raoh.

Ik Rupiya, Roshan gets a chance to experiment with different styles of music from down the ages. The number has a tinge of parody to it and belongs to that genre of songs which appear more enhanced when seen along with the visuals. Sudesh Bhonsle excels in this song and is supported by Kirti Sagathia, Bhavin Dhanak, Labh Janjua, Rahul Vaidye and Jimmy Moses who add to the vigor in the song. The song is basically a fun number.

 
The album ends with singer Ankita Sachdev singing the national anthem. There is nothing much to say except for the fact that it has been well rendered by the singer.

That said, the music of Krazzy 4 is in place with a couple of chartbusting numbers and some melody songs as well that suit the mood of the film.
