Yup. Take me for example. I hated Literature when I was in Secondary School. But somehow fell in love with it during 'A' Level.
But one thing for sure, till now I still have a strong dislike for Chemistry and Physics.
Really? I love the physical sciences myself.....
Anyway, about rap.... Although I admit it's not exactly my cup of tea, it is in a way, a subset of poetry. I've always seen songwriting as a special form of poetry. That includes rapping. Songwriting, however, is much more difficult for you've got to make string the words into a coherent tune.
True, you've got to harmonize the words in any form of poetry, but it's much tougher with songwriting.
