Isn't the term 'guilty pleasure' is used only by people who are ashamed of liking something mainstream?

I had no idea whether to post this on the RP section or Movies, both
have f**king up themselves w@nkers, so I'll do both. I'm in an angry
mood, 'Burn' by NIN is on repeat...

So in the music sense, you have your pop artists such as Ke$ha, Adele
or whatever, you have your mainstream rock artists such as Linkin Park
and MCR, anyone that does not kiss the a** of pitchfork media on a
daily basis... and god forbid if someone likes them, they have to call
it a 'guilty pleasure' to stop being stoned from hipsters who live on
a diet of indie rock bands and their cliched politically correct,
suffocatingly left wing lyrics *cough* Arcade Fire's The Suburbs
*cough*

In the movie sense, you have awesome movies such as Planet Terror
being called a 'guilty pleasure' because I don't know, they are
actually FUN movies and now Titanic is considered one despite it being
one of the greatest love stories. Sorry its so mainstream!

Seriously, RP, if someone ever calls your favourite novel, movie,
song, fast food place, clothes shop a guilty pleasure, do not hesitate
to scream or rant at them.

BQ: Favourite movie that made truckloads in the box office and
wouldn't hesitate to put in your favourites? (Titanic for me)
BBQ: Favourite song that is very angsty? (Head Like A hole- Nine Inch
Nails)
