MySpace may have become irrelevant as a social website for ordinary users, but it is easiliy the most important site for web sites for musicians: everybody who remotely means anything in modern music, has a (heavily personalized) page up on MySpace, with a few mp3 files up for streaming; sometimes whole songs, sometimes just 30 second samples.
True for modern music as you say, but for people like me, who like classical music, MySpace has little pull if it doesn't want to play the game of competing with FB as a general-interest social networking site.
And, as the FT noted earlier, Myspace has given up competing with FB for #s.
And most classical musicians don't need the pull of a social network to gain traction - they have a track record in symphonies, typically a strong network of other musicians from a strong music school, mentors and so on and so forth. Meanwhile, someone trying to "break in" to any non-classical genre, be it pop, rock, metal, synth-groove, indie-emo-core, anti-folk, shoegaze, etc, needs the help of a social network to garner excitement about their particular brand.
You don't need a brand as a classical musician, as you're usually just playing someone else's tune. (Unless, of course, you're both a musician and a composer, and so on and so forth)
So, of course it's not going to be much of a use to you, as you completely disregard most changes in musical style and composition (I personally love classical music, but that doesn't preclude me from loving other "modern" styles) over the past century or so. Your stubbornness in not exploring new aural sensations eliminates you from their target niche, just as the discouraged unemployed are eliminated from the unemployment statistics ;)
