Hey I’m 15, male from the UK just joined and Dinosaur Jr. are my absolute favourite band.
I think Dino’s best YLAOM which is also my favourite album of all time.
My order is:
1. YLAOM
2. Bug
3. Dinosaur
4. Where You Been
5. Hand It Over
6. Beyond
7. Green Mind
8. Without A Sound
But I still have tons of affection for Without A Sound.

I think their most underrated is either Dinosaur (one of the best albums I’ve ever heard but no one seems to think the same)
or
Hand It Over (not much of a dip in quality at all, although it was the first I heard by them so I understandably have a lot of affection for it)

EDIT : Woops, I apologize this should be in the songs/albums section
