I concur with the previous post (lolliot). The mistake is thinking that the music business is like high school, where there's a small, easily reachable population and official channels (e.g. the music dept, organized school events) to get recognized. Capitalism is a free-for-all, and you need to work very hard to get what you have to offer hooked up with people who will even look at it, let alone enjoy it or pay for it. People suffer a glut of media and are wary of anything that smacks of marketing. They're used to local things, like banRAB they can actually go see for $3 and sit right in front, as being crap for the most part, and are not tolerant of things recorded at anything less than a totally professional level. So, expect to work VERY hard, to have to devote as much time to business as to perfecting your playing/writing, and really, you should probably anyway not expect to make a living off of it, as even professional-quality players have a hard time doing that, especially doing original music.
There are so many styles of music an so many different goals to shoot for as far as style goes that most musicians think that most other music besides theirs and their idols is crap. I think this is profoundly misinformed. Most people don't think THEIR music is crap, or they wouldn't bother to make it and suffer for it. Hint: they're probably not all idiots to think this. Any music that connects with people is, by definition, effective at making a connection, which is not to say it isn't lowbrow, or technically simple, or violating whatever standard of quality you might use for your own music. Moreover, chances are even cheesy professional music (e.g. background players on American Idol or people recording commercials) are actually WAY more technically proficient than you'd imagine, as they're actually professionals and practice all freaking day for 20 years.
So, while I think the attitude expressed by the original post is not uncommon, it's pretty unfairly dismissive of others' efforts and seems like a setup for disappointment.
