I would imagine quite a lot of people do, considering you're own opinion an all. I currently have my own opinion that i have the best musical taste throughout my uni (without obviously knowing everyone, and of course my own opinion/taste on music).

About a good year ago i could name a few people who i believed had more 'developed' music taste than mine, music that i knew in a year or so i would love. I anticipate a few comments that derrogate this viewpoint, and if so i would be willing to respond to anticipated comments when they come about.
