Where do I find the music I PAID and downloaded of napster?

I know you can use napster to open the music but recently Ive had to re-install my os which means I can only download the songs 1 more time (ive had to reinstall it on my laptop too). So I tryed to burn the music onto a dvd (1. Because I dont have any blank cds. 2. Theres too many song to get onto a cd) but it wouldn't let me! (If you know how to burn music of napster onto a dvd plz tell me). So now I want to know where I would find the music in my computer! Thanks!

nvm found it lol
