Sorry, I'm not sure I understand, if you get something that was uploaded to rapidshare, megaupload, etc. you can download the song or video without fear of being caught?
Rapidshare, megaupload and the sites usually catch it and remove the files. Dont know about the fear of getting caught. I dont go and download every library, song or album there is. If I hear a song on the radio that is catchy, I'll get it and leave it on my phone as a ringtone. if I'm bored, I'll get rid of it.
Torrents are much safer and also better quality. Only download torrents with a decent amount of seeders and leechers if you're worried about being safe.
