Hold up. Apply the same thought exercise to video games as opposed to music.
Certainly you shouldn't care about what other people think about your tastes, but there is something to be said for being a well informed consumer.
If this post was prefaced "I like first person shooters, but really critically panned ones/mainstream (ie Homefront).

Sometimes it is just knowing where to start with something when you are venturing out of your comfort zone. If you like Pop music there are loads of options - Kpop, Jpop, Scandinavian, BritPop, all sorts.

You could start at worse places then Katy B, or in a more club sound - Icona Pop
