Surprisingly I was shocked by most of these. I knew Dolly Parton's I Will Always Love You. The most unexpected to me was Sinead O'Conner. There is so most emotion in that song, how could it not be an original. Signs of flattery. I was going to say I was super surprised with Stevie Wonder but I don't think that counts. Joan Jett really? Still a classic. Maybe we shouldn't be so hard when we hear someone covering a tune.
