Plant ID: Currant, Honeysuckle, deadly nightshade??

Looking at a property we're interested in buying, and saw this very mature berry tree.
I tasted half a berry, and it tastes & looks like currants.
However, the leaves aren't even close.
Leaves look like an invasive honeysuckle, but the berries don't really bunch.
Deadly nightshades have single berries, but I think they're black.

One thing to note.. the first picture is taken above me. It's not some small bush. I really thought it was a tree, but couldn't verify due to underbrush.
Location: Tri-State area, (IA, MN, WI)

Any help would be wonderful, thanks!

Autum olive or huckleberry? Definitely not belladonna. If you think nightshade, from observation, it may be because huckleberry is a common name, but yet still a night shade. Red huckleberry tends to be from the NW, but you kinda match that climate.

Definitely not a currant, honeysuckle, or nightshade.

"Invasive" Honeysuckle,
we have tons of them here in MN. I've never seen one with bunching berries like you described, ours look very similar to yours.
Not a terrible plant, our chickens enjoy them for shade, birds and bugs like the flowers and berries.
