>I like music in genreal. I listen to different kinds of genres because I like music.
>I only really like this one genre, but listen to a lot of songs in this specific genre because I like music.
This is reasonable
>I like music. Music is my shit. I only listen to this one song on repeat. I have this other song here if im feeling adventurous.

>I like beer, so I only drink this one beer I like, or the cheapest one availiable. Its beer after all! No big deal!

A hipster is someone that compulsively follows the newest trends or fashions, and outright refuses to do anything "mainstream".
Drinking or eating what you like to eat is not hipster per se, as long as you're doing it because you like it and not because the beer youre drinking is the hottest new shit this week.
