Wait a minute. Canada isn't in Europe. (Theory of a Deadman!)
Also, not all musicians from the U.S. are like 50cent. Stevie Wonder, BB King, Herbie Hancock... not going into this.
Let's see...
Jamiroquai, Zero7, the Brand New Heavies, Joss Stone, the James Taylor Quartet are the ones I can think of right now. And right now I'm going back to homework, so that's all I'll think about this for tonight.
Oh and of course, The Beatles and individual members - Paul McCartney, George Harrison, John Lennon... perhaps not Ringo, he hasn't had a great solo career and I haven't heard any of his solo material.
