Well, if one is an obsessed NIN-fan (which is totally fine) and
idolizes the band so much by forcing another or a new friend to
listen to NIN then one would think of the band as an absolute artist
over everything else in this world.
I used to be that way when listening to Green Day, it seemed like a brand new
experience and at the time a new start to revealing an absolute like..
There's in fact more music and artists which I can truly appreciate based
on specific genres. (yes i dislike certain genres, one having disliked simply for
racial purposes).
As long as you notice similarities between new people and/or friends
(think like last.fm would detect similarities between other users), then
you can share those similarities.. either by looking at their attire or
by means of good communication or similar interests.
I only post links to NIN videos from YouTube and share it via social
networking sites to share music, all legal

and sometimes I
succeed in convincing another to appreciate it.
You're free to likes and dislikes, however if there are no similarities
between one another then there's a probable negative correlation
