So after a couple months of observing, I have noticed that people's tastes in music gradually evolve. It's very gradual and it can take from a month to a couple years.
For this observations I observed 3 subjects. All of them my friends.
Subject One is interested in Rock, mainly Classical Rock. Like 3 Doors Down. Awhile ago I got him interested in a little bit of Megadeth, but for the most part, he still listens to the same rock bands.
Subject Two listens to Rap Metal and a little bit of Rap. The Rap Metal bands he prefers are Slipknot and Disturbed.
Subject Three is interested in Deathcore. Previously he used to enjoy Death Metal.
These observations brought me to a conclusion.
Given certain circumstances, in Today's Day and Age, there are three types of ways you can go with music tastes, and therefore change the type of person you are.
Everyone will start out listening to everything, experimenting in a sort. Eventually, they will move onto Rock, they will start to listen to bands like Subject 1. Then eventually, they will move onto Heavy Metal, like Megadeth and old Metallica. Then the paths can start to split. You can either start listening to Rap Metal, or you can start to listen to Death Metal.
If you listen to Rap Metal, you will eventually gain the mentality of a person who listens to rap, and eventually listen to Rap.
If you listen to Death Metal, you will eventually start to listen to Deathcore music.
You may be wondering what the third type of taste is for today's type. This starts out in the experimental stage of your musical tastes. During this experimental stage, you will listen to Rock, Rap, Metal, Punk, etc. The main lure for the third path is Alternitive Rock. This path will lead to either Punk or Emo music.
Does that sound about right?
