My favourite group of all time is
Rush, with such great hits as Emotion Detector, Ghost of a Chance and Red Barchetta. I prefer the older stuff (late 70s, 80s and early 90s). I find http://www.canoe.ca/JamMusicRush/home.html has some up-to-date info on the group and what they are up to.
Lately, there are various songs that are stuck in my head, like the classic song remade by Pearl Jam, Last Kiss or other favourites of mine, Wind of Change by Scorpions and Love Hurts by Nazareth. The Foo Fighters are a great group with hilarious videos, such as Learning To Fly and Everlong.
The Tragically Hip, a very popular canadian band, has many hits, some of which are Bobcaygeon, Ahead By A Century and Music @ Work. Even though they were from a few summer's ago: Lonestar's Amazed, Santana's Smooth featuring Rob Thomas, and Soak up the Sun by Sheryl Crow.
There are so many more, with most of them listed below. I plan to continually expand this list as I find the lyrics to my favourite hits of today and yesterday.
