How to start anew on iTunes?

So recently got an iPhone 4 for Xmas, after getting more accustomed to it I decided I wanted to get some music onto it. Unfortunately when I got onto my computer my iTunes was a clustered mess of horrid music added by other members of my family. I want to start again on iTunes with only the music I like and nothing else, how can I do this?

Open your "My Computer"… Look for "My Music"… Open My Music > Open iTunes Folder.

Delete any music you want to get rid of.

or

Open iTunes > highlight and Right click on song or groups of songs and then click delete.

either way, the music will be gone.

You need an iphone lession course
