vulnerability?

Im not really sure where to post this, but o well.. On the first page, about the napster vulnerability where people have the napster to go thing are able to burn the songs, what exactly is the vulnerability and how do they do it? Right now i have the napster to go and convert them to mp3 so i can put them on my ipod, just it is slow.. is this the way they are talking about?

 

ok thats similar to what i am doing.. i use a program called tunebite, and it takes however long the song is.. i use tunebite because i heard the quality is better than the winamp way to do it.. i thought maybe someone found a faster way.. how would they stop this?

 

hey im not complaining lol
I dont listen to much music, so when i do want a song, i just use that.
