Which current musician/band that IS popular deserves their popularity because of their talent and songwriting?

Tool.

Every member is at the top of their game, and it all comes together so exceptionally well.

I think Kendrick Lamar's popularity is totally well deserved.

Aside from that:

• Aurora
• Bonobo
• Billie Eilish
• Lorde

And more...

Deftones

Sleep Token

Absolutely incredible band

Hozier

Father John Misty

SZA

Tyler Childers

And oh my God, the juggernaut that is Fontaines DC

ETA I agree with Future Islands.

Vulfpeck is a musician’s delight. Their MSG concert was one of the best I’ve ever seen. Technically great as well - single camera, one shot.

Shout out to Ren whom I genuinely believe to be a generational talent - someone who has the potential to alter the course and content of popular music going forward.

If we're talking top 10 charts music (Taylor Swift, Rihanna etc.) I'd say Billie Eilish cause she's probably the only one who writes and records songs on her own as far as I know.

Bob Dylan is still around and got a Nobel Prize for his songwriting, but I can't tell if he meets your critereia.

Gojira have become fairly popular (I think). They're incredible!

I'm about to see Dead & Company in August, though I highly doubt that's what you meant by current.

I have no clue what the kids are listening to these days. Now get off my lawn.

That said, Goose is excellent if jam bands are your jam.
