This is a little different.

If you go their youtube page you’ll see they’ve done several Beatles songs.

Slowed this much it sounds a bit like a whale-song chorus. Not for foot-tapping, but maybe for background/relaxation. I’ve played with slowed songs before but I’ve only gone to 3/4 or 2/3 speed; Linda Ronstadt’s “You’re No Good” gives me the mental image of a singer in a black dress, single spotlight in a smoky bar when it’s slowed down. Elvis’s “Burning Love” is definitely more bluesy. There are a few Heart and Blondie songs I like as well (some with the slowed voice pitch, some preserving the original; the Amazing Slow Downer app I use allows one to adjust that. However, it’s limited to 20% of the original speed, or a slowdown of 5x. Still, interesting sounds.)
