The Highway music album has nine tracks.
Patakha Guddi, sung by the Nooran sisters- Jyoti and Sultana, is a Punjabi song celebrating the wild spirit of Alia's character Veera. The male version of Patakha Guddi has been sung by Rahman himself which moves from Sufi tones to a hard rock number.
Rahman also sings Maahi Ve which is a ballad picturised on Alia and Randeep as they go through this journey together.
Alia takes the microphone singing the lilting lullaby Sooha Saaha where she is joined by Zeb Bangash from the popular duo musicians Zeb and Haniya. Haniya plays the ukulele in the song.
Kahaan hoon main has been sung by Jonita Gandhi and is a soulful song of self-discovery.
Wanna Mash Up? written by Kash and Krissy and sung by Kash, Krissy and Suvi Suresh is a surprise - a groovy western dance number all in English with rap and reggae.
Implosive Silence is a musical piece which tries to capture the sounds in Alia's character Veera's head as she travels on the Highway. It has vocals by Jonita Gandhi.
The opening refrain of Tu Kuja is from the famous Persian phrase but thereafter it is a shudh Hindi song inspired by the Amir Khusro song 'Kirpa karo Maharaj' in praise of Moinuddin Chisti. This is beautifully sung by Sunidhi Chauhan.
Heera sung by Shweta Pandit are traditional couplets by Sant Kabir.
According to Imtiaz, "We have played on melody and simplicity - trying to get right the balance between lyrics and music."
"Really enjoyed working with Imtiaz and his team again ...May God bless us with love and success!" adds the maestro A R Rahman.
Highway, produced by Window Seat Films and presented by Sajid Nadiadwala, will be released worldwide by UTV Motion Pictures. The music of the film will be available on T-Series.
