The nice thing about ripping a copy is the ability to strip out all the previews and anti-piracy bullshit. Not saying I would do something so immoral, but I've heard it can be done. Yeah, that's the ticket.
I've discovered a lot of new music (to me) over the years on the "Music Choice" channels on cable TV, and back in the Napster and WinMX day's looking at other peers shared music folders. In the late 50's I was turned on to new artists through American Bandstand, AM radio in the 60's, FM radio in the 70's, and MTV in the 80's and early 90's (when it was still a Music Channel). Today I find good new music via torrents.
