I've tried every styles available in IRP but couldn't find a close enough match for songs such as "Natural Woman" (Aretha Franklin) or "If I ain't got you" (Alicia Keys).
The pop styles available are either swing 16th notes or straight (even) 8th notes based.
No swing 8ths styles (except in the jazz category) are actually available.
The closest I could find is the "two/four swing style", but it goes into walking on chorus, which doesn't fit the style at all.
