The one I use is MP3videoraptor, it gets off the music, videos and audios, from music sites and even from internet radios. It's cool cause I don't have to get a sort of music player for playing this stuff cause it can convert the files into the formats I need so that they can be played on other music devices. I use it for a long time so far never had any probs with it.
