Chad Kroeger has done a few collaborations over the years and all of them have been awesome. He did 'Why Don't You and I' and 'Into the Night' with Santana. Chad's vocals and Santana's guitar playing are both outstanding. He also did Hero with Josey Scott, Tyler Connolly, Mike Kroeger, Matt Cameron and Jeremy Taggart for the Spider-Man soundtrack. He also did the song, 'Pornstar Dancing' with My Darkest Days, Zakk Wylde and Ludacris. In my opinion, Chad has done some awesome collaborations.
