I'd consider bad taste in music to be if you're listening to something not based on it's musical merit but instead on some other factor, such as image, lifestyle, popularity etc. I've been quizzing people who like music that I think is shit, because I'm genuinely interested in how they can stand to listen to it, and I've come up with only one answer.
The reason that people listen to the incredibly shitty deluge of pop and rap thats out there isn't because they like the music, it's because they like whats associated with it. You obviously can't pop in a metal cd and start dancing to it in a club atmosphere; it just wouldn't work. The people who like the kind of music played in clubs and on mtv or whatever (which I consider to be bad taste in music) don't actually value it for the music, they like it because it allows them to dance and to meet people.
As well, the less educated someone in musically, the less I respect their tastes in music. The success of bad music such as pop and rap is because it's so incredibly easy to duplicate; so much so that someone with no musical talent AT ALL can still manage to convince themself that they're singing along just as well as the singer himself. No one with no guitar training will pick up a guitar and believe that they can easily rip out a Sonata Arctica song or whatever, but people with no vocal training will still sing along with Britney Spears or 50 cent or whatever people are listening to now.
So therefore: bad musical skill = bad music taste because you don't value the music for the music itself.
QED
As I've said before, generally people want music that's simply "pleasant" to listen to. Simple lyrics they can sing along to, simple beats they can dance to, etc. They want music that they can listen to with their friends while talking, laughing, etc. without really having to think. MTV knows this to a tee, and that's exactly why they often promote the kinds of bands that they promote.
From my experience, most people in the mainstream will buy a "hip/trendy" album, and not even remember a single song from it other than the "Hit Single." And then, after about three years, they'll have totally discarded it for something else.
Of course, there are acceptions (Tool, Radiohead, etc). But this is generally how it is in the mainstream.
