Query: Obsession

Since first hearing John Mayer several years back, I have become almost obsessed with all of his songs, especially his lyrics and phrasing---I find both almost hypnotic as I listen and relisten to this new CD--in many ways far superior to his first in it entirety. Just when I get comfortable with a song, and his style, I am surprised by either a change in tempo and or orchestration--and his lyrics to me are almost as good as Bob Dylan's--that's maybe why I like him so much--the subtle ranges of his musical delivery when coupled with his lyrics take me to places Dylan has in the past. I find myself singing his songs all day and leaving the cd in the car player for days--and I do not skip around, I let the CD go from beginning to end.
