R&B, maybe Motown, heavy piano riff, female vocalist, maybe girl group from 60s/70s
 

Earworm all day.

I remember it as some Motown/R&B song... like Martha & The Vandellas or something akin. Mid or late 60s to very early 70s? Upbeat.

Possible lyrics of chorus

And now you've gone away
[backup girls] ...gone away
Tell me if I am the ooo-nly one

Piano riff:
dah-dah-dah dah-dah, dah-dah-dah dah-dah
