Being Made to like Music I Hate

I recently have been experiencing a new phenomenon of having songs i HATE (for example, A piece of me - Britney Spears) drummed into my head so much that i start to LIKE them. As a result i now have songs on my itunes that i would never have had a year ago. previously my tastes were strictly limited to folk and indie music, but now to my horror Artists like Estelle, Britney have made there way into my recently played list i am distraught! but on the other hand a more varied taste in music shouldn't really be considered a bad thing.
