I think that practicing scales is often overemphasized -- at least the idea of practicing them in isolation. Not all notes from the scale of the key signature are going to sound good to land on. Learn the chord, then the arpeggio that goes over it, then the scale. This will help you learn to land on the right notes and emphasize the chord changes. The notes in the scale outside of the arpeggio are just notes to use in passing. You could totally do this exercise with Bad Moon Rising.
