It was sung by Shaan

Music School released in 2023.

If the seven songs from the film were arranged in the alphabetical order of their durations, Aa Kar Tu would be the first.

And if they were arranged in the ascending order of their durations, it would be the third – it was four minutes and a dozen seconds long.

The song, which was alternatively titled Christmas Ki Raat, happened to be the only male solo on the film’s soundtrack – Shaan lent his voice to it.

The song, which was written by Dr Sagar and Raman Raghuvanshi, was composed by Ilaiyaraaja.
