Here are some tunes which just don't work for piano karaoke ... and the reasons why!
No Such Thing
The solo piano just can't approximate the slammin' drum-and-bass-heavy full band groove and the very active hooks on this tune!
What Does the Fox Say
This tune is electronica-heavy and constantly driven by a prominent four-on-the-floor beat. The piano just can't replicate this kind of groove in a satisfying way.
The first section of this beloved Queen tune works beautifully -- until the crazy mid-section (around the 3:00 mark), when the multi-layered background vocals, crazy harmonies (which change just about every beat), and iconic guitar solo usually cause vocalist, pianist, or both to crash and burn!
