Tame Impala's "Solitude is Bliss"

Wasn't there a recent pop hit by Miley Cyrus that followed that theme? Something about giving herself flowers.

Oof, this is a tough one. Maybe...

Billy Idol - Dancing With Myself

Belle & Sebastian - I Don't Love Anyone

And in a more "society won't hold me back" kind vein: Black Flag - Rise Above

Give „Medication“ by Garbage a try. Might not exactly fit, but maybe you like it.

Bif Naked - I love myself today

Does

Dream Evil - The book of heavy metal

Count? 😂

Don't need no flashy house, no kids, car or ugly wife

The only thing I want, is what my parents don't

Need no widescreen TV, no in all honesty

The only thing I want to be (to be or not to be)

In the book of heavy metal, in life, metal!

"D-A-D" (Disneyland After Dark} made a couple that might fit.

"Bad Craziness" is probably the closest.

"Sleeping My Day Away" could also work.

"Home Alone 4" is perhaps a little bit melancholic but not a sob fest.

Honorable mention is; "I Won't Cut My Hair" it doesn't fit the prompt, but it's good for rocking out alone at home.

Does it need to be rock? 'Cause "Isobel" by Björk is a banger too.
