Reusable lyrics

Having listened to the Tamil and Hindi versions of the songs of the upcoming movie Enthiran (Tamil)/Robot (Hindi), I have come to the following conclusion.

Lyrics which have no meaning are excellent candidates for reuse. To illustrate the case in point, here are some snippets (from the track title itself).

Arima arima
Kilimanjaro (and in the same song, Mohenjedaro)
Boom Boom Robo Da

One way to achieve it is liberally use English words or proper nouns.

Hmm!  looking at this lyrics page, we can see more such instances...  Neutron, electron... and so on.

Wonder, if  lyricists get paid separately based on the number of languages in which their lyrics are used
