EDM isn't just upbeat happy dance music with build ups, which is the only type you hear on pop radio. It can also encompass slow, trance like euphoric progressions which CMB has with the piano riffs building up to a basic synth chorus. TBH, none of Kelly's songs are even close to truly being EDM but CMB's production is heavily electronic influenced. Stronger and especially PLU are more pop-rock.
Edit: And I haven't been listening to anything other than Natural Woman (2013) too
I need more singer-songwriter classics like this
