Well would you say the same to when you listen to Justin Bieber, Rebecca Black, country music*???* I certainly wouldn't.
For the examples I listed above, the more I hear it, the more I hate it with a passion. So how do you explain that? =p
Jokes aside, as for the music I hated initially but ended up liking them, I find that it is only the case that the more I listen to it, the more the lyrics makes sense. Then somehow as if in an instant it is just clicks and I find that everything about the lyrics fits in with the tempo and musicality of the background music, instruments. That is how I find I end up loving the song.
What I'm trying to get here is, I think it is more to do with perceived expectation or maybe just peer pressure?
Let's say this scenario: you hear a new song initially and you expected it to be of a certain standard. It doesn't quite cut it. So you underestimate it. Then it appears on the radio alot more often and your friend claim it's pretty good. You hear it a several times more but now with a lower expectation of what you had of the song. Then you slowly find "it's not that bad" and get an more and more slight inclinations towards that song.
I find this apparent to not only music but a perfect example of mine would be a person's looks.
For me, I found this true on many occasions. I meet an average looking girl in class but the more I see her, I find she actually looks quite hot. But the opposite also happens for me i.e the more I see a hot girl I find she looks average.
You get me?
