In a lot of forums and imageboards[1] people definitely always have the "same taste", unless the forum is huge. [1] From what I can remember, 4chan's music board users have their own "accepted" artists, though a smaller group of users go against them and choose to listen to more obscure, random music (I used to fall into this category—I was a silly 17 year old). But in general, you can assume a frequent users know and likes a set of albums. Reddit might be the same, but the general subreddits are too large and the smaller ones are well, focused on a specific genre.
