The DJ has done a commendable job in selecting the underlying scale of the mash up. As a result, Po Po (higher scale than OST), SOS Title Trax (lower scale than OST) and Desi Beat (lower scale than OST) are catchier than their original versions. But the USP of the mash up is the PO PO portions, jisne 'chakde phatte' in Punjabi ishtyle. The DJ has chosen a catchy underlying scale and then modulated the vocals. Catchiest part is PO PO followed by SOS from 0.39 to 0.41, PO PO followed by Long Drive Pe Chal & Hukkah Bar from 0.45 to 0.55, 1.33 to 1.42 & 3.13 to 3.29

Its a great job by the DJ, because generally, its easy to remix a single song than making a mash up of songs, since lot of editing is required to take selected portions of different songs which may have different scales, and then all combining them all, on one scale. This equires a lot more creativity than just a normal remix.
