What I said before. :)

Like I said, it's all a matter of opinion. Whether a song is good or bad is all a matter or opinion.

it is subjective but it's also objective too cause there is alot of music I wouldn't want my daughter to listen to but for the most part we have alot of the same taste in music, if it weren't for her I would just stay in the 80s & would miss out on alot of other good music

different opinion for different people; i love 60's rock, blues, psychedelic, 50's rock, etc. my friends love all the new stuff.
it just depends on the taste

It's all based on opinion,whether a specific song is good or bad is only based on opinion and that's about it.

Super subjective! No one has the same tastes, especially in music; there's just so many different styles out there. Not everything is for everyone. But then there are people who just love it all. Some people think rap and dub step is just senseless and vulgar noise whereas some people see it as classy and catchy. Some people think classical and folk is boring other people find it fun. Liking or disliking a song doesn't mean you have good nor bad taste at all, it just means you like what you like.
