Can I use the school computer to download music with explicit lyrics.?
That does not sound good. Are you aware that using the school computer to download music goes against school rules?
I am aware, but I don't give a shit.
You are making a choice to have the computer taken away from you if you use it inappropriately. You should use the computer to complete your assignments and use other educational programs only, instead of downloading explict songs on your school computer.
Shut up, I do what I want to and nothing will happen.
They have ways to find out when a student has used a computer inappropriately. You could even get expelled when they find out.
