funk is a form of R&B. if those songs aren't funk, then how could anything james brown ever did be considered funk?
"By mid-1960s, James Brown had developed his signature groove that emphasized the downbeat – with heavy emphasis "on the one" (the first beat of every measure) – to etch his distinctive sound, rather than the backbeat that was familiar to many R&B and soul musicians. Brown often cued his band with the command "On the one!," changing the percussion emphasis/accent from the one-two-three-four backbeat of traditional soul music to the one-two-three-four downbeat – but with an even-note syncopated guitar rhythm (on quarter notes two and four) featuring a hard-driving, repetitive brassy swing. This one-three beat launched the shift in Brown's signature funk music style, starting with his 1964 hit single, "Out of Sight" and his 1965 hit, "Papa's Got a Brand New Bag."
