Do you understand the words to the Mus U listen to

The words/message many times is hard to understand with some artists.
Dave Matthews at times is like what is he on about?

Paul MaCatney is easy on the words and is quiet funny at times. Most singers mumble their words and frankly I think they have no real message worth thinking about.

PM Mistress & Maid is a message that speaker to the issues of the heart and you can understand the blinking words. Another one is Hope Of Deliverance. Makes the song that much better when you hear/understand a real message.

Any take on Jethro Tull?
