I'll be happy when rap is finally in the grave. Not to mention so called 'alternative' bands with guys who only know basic open chords and use a lead singer with a fake British accent.
The nice thing about the internet is that musicians like myself can finally publish our own works to a worldwide audience. The drawback is that every other guy with a computer thinks he's a musician these days and you not only have to compete with all the crappy amateur stuff, you now have to compete with this mentality of people who think that music should be free.
As far as crappy music goes... nobody has the desire to really learn an instrument anymore because they can do everything digitally and copy & paste everything.
There's so many choices for kids in terms of entertainment that most of em don't do what we did when we were younger.... sit around in a bedroom for hours trying to get away from your parents and the only thing you've got to do is listen to one of your 4 or 5 albums. You listen to em until you wear them out and know every note. You sit down with your guitar and play for hours because there's absolutely nothing else to do.
Now it's instant gratification. Download 100 songs, listen to them once and then throw them out and start again & to top it off, it doesn't cost a cent.
Get tired of music and surf the internet or watch 400 channels on TV... download some pirated software and compose your own rap tunes then play Nintendo all night.
When a teen finally goes to hang out with friends, there's no incentive anymore to get together and just hang, maybe smoke a few J's and listen to music looking for all the hidden meanings in the latest Pink Floyd album. Now if you want to know all the secrets behind Dark Side of the Moon, all you have to do is surf the internet.

One thing that has interested me lately is Apple and their involvement in the music industry.
The idea of making songs available for $1 per download or a monthly fee makes it easier for guys like me to someday be able to post my own tunes online....supply a lo-fi version for listening and then offer a CD quality download for $1. This attitude that MP3's should be free to download and freely infringe on copyrights has got to end first though.
