Query: Major disappointment

Martha, Martha, Martha! I thought you were on par with your brother, but I guess I was mistaken! I am fascinated and enamored with Rufus and his repertoire, so naturally, I was willing to give Martha a good "college try". Well, I found this music to be boring and the lyrics just not "there". This one's going to Goodwill. There is MAYBE one song that I would listen to again, that might grow on me over time and make it into my "rotation". But Rufus has something indescribable, for me, that Martha just "ain't got". I think she should stick to being backup for her brother, as their voices blend beautifully. Martha, hat's off to you for trying to find your own voice, but you should cede the crown to your brother!
