Townsend is incredible. Any one who can write a song as beautiful as "Behind Blue Eyes" is practically beyong compare.
Here's selection and some reason for them.
Bob Dylan - for "Times They are a-Changing"
Nina Simone - for "Don't Let Me Be Misunderstood"
Pete Townsend - for "Behind Blue Eyes"
Roger Waters - for "Time"
Trent Reznor -for "Hurt"
It's not a top 5, 'cause I've missed out some people, people who's lyrics are important to music as a whole and people who are important to me, but these 5 would feature somewhere in any top 20.
