Karamungikar's law of music

Last Friday, I was at Show Off, hoping to get a 'The Doors' branded T Shirt. There was this guy who was showing me T Shirts from a huge stack. As he showed one by one, he asked me. "Saab, yeh rock band boleto kya rehtaa? Picturaan hai kya ?". Yeh poorey bhooton ke sarka kaikoo tayyar hote?". For a moment, I felt I should laugh. Then I thought, 10 years back, even I was like this. I will never forget the day when my mom bought me my first English/non Hindi film audio cassette, which was Khaled's album with the song Didi. I was in the 6th standard.

There were the days when I thought Michael Jackson's Dangerous was the best ever album. I was in 8th standard then. In the 9th and 10th standard I felt that Dr. Alban was god and there cannot be a better album than One Love. I still love one of the songs. i thought Peter Andre and Jennifer Lopez were the best one can get to hear.
My 'Rock' journey began in 1998 when I bought Pink Floyd's The Division Bell after I saw the music video of the song High Hopes on our 1984 model Uptron B/W TV. There it all started.
And the current status is, I listen to Pink Floyd, The Doors, Led Zeppelin, Nirvana, and Metallica.

Please note the following points:
The Doors - inactive after 1971.
Pink Floyd - their last performance with all members together was in 1985 when I was 3 years old.
Metallica - their best song 'Fade to Black' came when I was 2 years old.
So, relatively all these songs are quite old. But then, does this give rise to a theory that,
'The age of your present favorite song or the band is an exponential power of the number of years you have been seriously listening to music'
(or)
'The age of your favorite rock band is a factor of your experience with music'
(or)
'Rock music, is like wine. The older it gets, the tastier it gets.'

Well, shall I call this the 'Karamungikar's law of music' ?
