Yes you're right, a lot of artists peak at a certain stage. But then there are new artists who take their place. For me country mostly stopped giving me that in an available radio format.
"I Feel Lucky" was a damn fine song, as is any song that name drops Lyle Lovett and Dwight Yoakam
I mean, substantial, no, but it was really just a party song, it sounded great and the lyrics weren't at all awkward and had their own sort of ambition. Like "Down at the Twist and Shout".
