what is the difference between good and bad music

All music is good, until purchased....if you know more than 3 people who own the same cd, it can't be any good. for vinyl, I believe the number is 2.....with the declining sales in the music industry, it is projected that these respective 'is music good? #'s' will be down to 2 and 1.........hope this clears everything up

To borrow from a famous dog trainer: "There is no bad music only bad listeners."

Rap may be good, but is it music?

I am with PCS about being like Albertporter when I grow up. Awesome collection of artists that makes me want to check out the ones in your list that I am not familiar with.

the changeability of personal taste is fascinating: how many times have we pulled out a piece of music we used to love/not love, only to find that our feeling about it has flipped 180 degrees? it makes selling 'unwanted' CDs/LPs a risky proposition indeed...

another interesting note on this subject: some musical instruments (stringed especially) are just naturally louder and have better timbre when they are tuned properly. now how do you explain that? are there preexisting C#s in the universe?

albert: if you are open to Stockhausen, you might try to get your hands on Kim Cascone's 'Blue Cube' or 'Cathode Flower' - very cool computer-generated music by an associate of Angelo Badalamenti (Twin Peaks) or Jon Wall's 'Fractuur' or 'Alterstill' - music constructed of samples of 20th century composers (which doesn't sound sampled at all; it sounds composed and seamless)
