Oh, please mention who the artists are, maple leaf boy! We're all ears!

I'll just say my list of artists with signature tunes wasn't necessarily based on my favourite artists, or on whether I think their versions of the songs in question were artistically pleasing to me, or whether the songs in question are even songs I like. It was simply based on examples I could think of where a song is often associated with a particular artist, or a particular artist is associated with a song.
