How do you remove downloaded music?

[sxylegs]

Hi....
I have a couple of the music site that I have been downloading music from.....one is Kazaa....which I can do whatever I want to with the music once I download it. I can burn a cd or put the tunes in winamp and play them on my pc. My question is does anybody know how to remove the tunes from Musicnet or limewire. I used to be able to remove the tunes from limewire, but that was awhile ago. I have paid for these services so not to do anything illegal, but now i can play them but not make the cd's that I wanted.
Can anybody help???

thanks
