seedless berry

I would love blackberries, raspberries, etc.  The perfect berry would be blackberryish with NO SEEDS.  Is there any berrish berries with no to few seeds?

It seems you are in luck as there is such a thing as seedless berries.

Some raspberries are sold as “seedless”. European raspberry, Rubus idaeus, is an example but my guess is that it simply has small seeds.

These tall, erect canes yield extra-tasty blackberries with exceptionally small seeds.

Thank you for your suggestions.
I have the Arapaho blackberry you mentioned I can't tell the seeds are smaller.  I'm hopeful that somebody will some day make seedless varieties.  Mulberries are kinda like seedless blackberries.  Wonder if the weeping mulberry makes good fruit.  The non weeping varieties get so tall and the birds get them.

mulberries can be managed as an occasional coppice to keep them reachable. the weeping varieties are okay but don’t really make much fruit.
