I’ve seen lists of songs with deep lyrics, songs that are upbeat but depressing at the same time, songs not on the radio, and other things like that… But I have never seen a list of songs that are just super fun to sing.
Some examples of things I like singing are Lewis Capaldi, anything by Chris Cornell (though I wish I could have that awesome gutteral/growly sound in my voice), Cottonmouth, Nirvana, RHCP, Tool, etc. I love long sustains and just dudes and dudettes belting out staccato. The feeling of matching pitch and tone you get in your stomach and lungs as the sounds reverberate together is exhilarating.
We Want the Funk - Parliament. It’s straightforward, but there is a lower and higher vocal, both of which you can swap between in karaoke.
Be prepared to have the place singing with you.
