I think music represents one of the most unique art forms in the world. It's enjoyed by virtually everyone (unlike paintings, film, and sculpture which are commonly mocked), it cannot be consumed visually (unless a new art form like light or film is used to acompany it), and it can be extremely commerically successful in the modern world.
Music comes in many genres, and I think each genre is a decent set of boundaries on identifying and categorizing songs, but does it a bit of a disservice as well. I try and ignore a genre before I start judging a song based on a few characteristics that I find really important in evaluating a song, which are:
This traits are how I select music to feature on my music blog, and is also how I sort through music when I'm looking for new additions to my library.
I listen to many hours of music every day and have followed all sorts of music blogs and record labels to watch trends and see what is moving in the music industry. I find it really fulfilling.
