As far as I have been able to discern, there is no law that states that momentum must be quantized. It is defined to be a continuously varying function dependant on the velocity of the particle according to the relativistic equations derived from the Lorentz Transformations. However, this article: http://www.nemitz.net/vernon/MOMEQUAT.htm on the web puts forth on first glance a convincing argument for the quantization of momentum. I haven't analyzed the mathematics in detail but can anybody spot some flaws?
Thanks to Sanat Rath , I had the absolute privilege of listening to this superb rendering of Madari by Vishal Dadlani and Sonu Kakkar and an absolutely stunning composition by Clinton Cerejo as part of Coke Studio. Here's the official video. The lyrics of the song are interspersed with the meanings translated to English. Credits for the superb lyrics go to Manoj Yadav. Hope you enjoy it. Make sure you watch this in HD, it's worth the extra audio quality.

[Vishal Dadlani sings] Madari, Madari, Madari, Madari mera tu, Main Jamura re Jamoora, Jamura re Jamoora... Master, master, master * you're my master I'm an obedient assistant * , an obedient assistant... Madari, Madari, Madari, Madari mera tu... Main Jamura re Jamoora, Jamura re Jamoora re...
