what is the difference between good and bad music


my friend says rap is bad music. another friend says mahler is a terrible composer.

is it all subjective, i.e., a matter of opinion ? or are there standards which can distinguish good from bad music, however one defines these terms ?

if there are standards, can one specify them or refer me to a source ?

Tobias I 'll give a few of my top say, 10 favs. As the list after 10 represents not so much fav composers, as a few fav workd from the composer. IOW I only like a select few of Wagner's operas, Parsifal, Tristan And isolde, The Ring...and then even with those operas, only a very select few recordings. Can you see how this could lead to trouble among fervent classicphiles, and especially among Wagner fans. "you mean you don't like his opera, Flying Dutchman??? But WHY?" One should always have to explain.
Among all clasical composers of the past 300 yrs, i start at Vivaldi, though Corelli is of interest, there are few avaliable recordings, and the one to get is OOP. Should first mention, Folk music from the middleages , is pretty interesting at times. Thomas Tallis, but the recordings I like are OOP. I like a few from Bach, but not the dull Brandenburgs, way too conservative for me. , next is one mass from Haydn. Then I go to Mozart, most everything he wrote has interest ranging from some interest to profound. Then I go to Wagner;s 3 operas mention above. Wagner, the first modern composer. A few works from Grieg,, and a few operas from janacek, several of his works for chorus/orch.. Debussy a major fav, the next most important modern composer, after Wagner. Almost all of Ravel, a super favorite for me. Early Sibelius, pre 1905/sym #1 is OK. Syms 2-7 are of no interest to me.Moving onto Varese, most of second Viennese school, Schonberg, Berg, Webern. Richard Strauu has some excellent operas, select few, select few recordings. Karl Hartmann has some interesting syms. Shostakovich, most of his works. Almost all of Prokofiev. Almost all of Bartok. Some of Charles Ives works. Almost all of Vaughan Williams, select reccordings. Elliot carter, almost everything he wrote. I still have a fondness for some Rachmaninov. I see i missed Rodrigo's concerto's for guitar, select recording. I love Albeniz and also Granados solo piano.
Something from Chopin once in awhile, but not often.
Mussorgsky wrote a great first half in Boris, his Pictures at an Exhibition, with Ravel's orchestration ONLY, and only 1 or 2 recordings. The solo piano version is a bit weak.
Comming to the end of the 20th century, 2 very special composers for me are Allan Pettersson and Alfred Schnittke. btw Schnittke is equally important in music a sare his thoughts and ideas in the book, A Schnittke Reader, edited, interviewed by his close friend, Ivashkin.
I guess the foremention represent less than 1% of the major classical of the past 300 yrs. I'm not complaining. We all come from different backgrounds, and so our uniqueness will show through in our choices. As someone just wrote above, others too, its all about soul.>>>>>>>>>>>>>>>>>>>>>>>
btw please ck out a new Indie music group, a local group from Baton Rouge/LSU. Blessed Yes. Go to their web site and myspace site to hear their SMASH HIT (my choice of clurse) called Trace. This to me has soul. btw Blessed Yes did not win the MTV University contest. Which is another story.
After you hear Trace, post a note on my topic Blessed Yes. Be honest, if you don't like it, tell me so, if it needs work, tell me that also. I hear the few rought spots. But remember they are only 1 yr band.

All music is "bad". I only listen to test tones. Music is just too unpredictable to really enjoy testing wires with. I just can't understand you guys who purport to be audiophiles wasting your time on music.
Does society have the ears, the capacity to know just what is good/bad music?
Look at how long before Vincent Van Gogh was recognized as a ture genius of high art form.
I witness this same phenomenon in classical music. Some 20th century composers still have yet to be recognized for the superior genius they are.
It will take another 25 yrs+ to bring these composers to acknowledgment.
High genius is always far ahead of the slow poke masses.
