H.E.R. stands for Having Everything Revealed. The irony of that moniker is that H.E.R. remains a mystery. Scope her Instagram. You'll only catch little slivers of her face. She's made the conscious decision to stay hidden. It speaks volumes of her talent – she doesn't need to use her face to sell the music, she doesn't need us to care about that at all.
And you won't. With one listen you'll be shaking your head, clapping your hands, scrolling through H.E.R. IG life, listening to her recently released B Sides, the whole package that is H.E.R. hitting you like wow, just, wow.
"Let Me In" in its original form is a slow bobbing groove worthy of a thousand repeats – R&B heavy like a dense fog on a warm night, sensuality cooking under a full moon; very Drake, very Daniel Caesar (who's actually featured on this release), but ultimately very H.E.R.
KMB's edit speeds up "Let Me In" like proper house tends to do. After all, house is just fast R&B. His is the version I heard first, the version that opened the door to H.E.R. so that is the version I'm sharing.
It all sounds so magically romantic, doesn't it?
At any rate, whichever version you choose to fall in love with, enjoy.
