Expressing my anger

Music today sucks. I'm sorry, but it does. In fact, most music isn't even music. It's made on a computer. I dont think 50 cent, Christina Aguilera etc is music, it's trash. It's using a gimmick to sell.
I find it ironic that most pop/r&b artists do something controversial just when there latest album is about to be released:
Example 1: Janet Jackson. Unless I am mistaken she has recently released her new single, and a new album? Just two months ago she controversially exposed her breast at the Superbowl, causing all the media to pay attention to her, thus advertising her new stuff. Coincidence that her new record was set to come out?
Example 2: Britney Spears. Just about a month before releasing her new record, she shared a kiss with Madonna which was the talk of the town, and the media. Coincidence that her new record was set to come out?
Example 3: Christina Aguilera. Went through a controversial image change claiming "she wasn't being herself" in her previous album. Funny how then being a innocent popstar was the trend back then and now its dirty skank. In my opinion it's not being herself, she's just conforming to the latest trends.
Just think of a little preppy kid: "Oh my god! I've heard about what happened with him/her. I wonder what the cd is like!"
Bands like the Foo Fighters and Muse aren't conforming to what's popular because they truly love there music, and want to sell the music and not themselves.
How can people like Justin Timberlake and Avril Lavigne call themselves musicians when they don't even write their own songs (Avril only contributes slightly to her songs, she sits down with a guitarist), which leads to my next opinion.
Why in the world do we call these people talented. They dont write their own music. They only sing! Okay, you might say "Yeh man the voice is an instrument". Yeh, you could be right but if they have such good voices why on all their records do they need to be computerised with voice enhancers? Listen to Britney's Toxic. What the hell is that? These people sound ridiculous live when they actually do sing (a lot of them just lip sync and just do their dancing moves).
And when popstars write there own lyrics, I laugh my head off. Seriously, Jamelia's Superstar: "People always talk about eh oh eh oh eh oh". That eh oh bit is a cheap excuse for not finding a lyric to fit there. Man, that lyric is so deep!!!
I'm sick of people selling their sexuality and stuff and not their music!!!
Mock me all you want if you don't agree.
