There's a lot of recent music that I don't really like, but then again there's some I do like from now.
It's more a matter of genres then the time from whence they came.
Even so, I do find music from the '40s and prior to be preferable to most of the current generation's music.
(Though, in relation to Wobbuffet's message, I wouldn't say this makes me any better (or get any more 'cool points'? o.O) then anyone liking current music, I just don't particularly like most of the music nowadays - at least most of the generally popular music, though this is unintentional, not because I'm specifically trying to dislike popular music)
One of my friends says I'm close-minded for not liking modern music, this isn't true - I simply don't like most modern music just as a personal preference. (And, relative to the above paragraph, this is the music I like personally, so I'm not going to be liking something merely to get 'cool points' in the eyes of others..?)
By the way, I can't even hear Justin Bieber, because the human eardrum isn't capable of hearing such high frequency. ^^
