Watch that. Bon Scott and Brian Johnson are both good, but they are good in different ways. They just CAN'T play each other's songs.
Probably:
Artists:
1. Lifehouse
2. Simple Plan
3. Three Days Grace
4. 3 Doors Down
(Sorry. I have 4).
This is going to be a tough desision. I have so many favorite songs that I can not answer this question.
