Mr. Tambourine Man was a watershed in my life, after that I began to listen to "pop music", before that I had listened to... I don't really remember what -- kids' music? Maybe not actually kids' music, but... something that did not belong to the modern times. No Elvis, no the old-fashioned rock, because I hated it and still hate, not that music sung by those idiots with greasy brylcreem hair of the '50s, because I belonged to the '60s and the hippie generation.

Well, my English is not perfect, but you got the idea.

I remember vaguely but still clearly that I was sick -- I think it was a scarlet fever -- and the radio was on and I heard this, and I thought that I like it very much, and after that I began to listen... how should it called today? In the past it was called pop music.
