Oh ok, he's probably voice leading which would make it more common (I was assuming a particular chord sound). Assuming by 7M you mean the maj 7 of the chord, for that progression try:
G#-^7 /E then E7#9
Because of the randomness of the player however, the progression might not sound in exactly the same position (or voicing) when the two chords change (either in the same neck/fret position of a guitar nor in the same note position on the piano sound) so it might not sound like voice leading each time. We have taken some voicing leading into account as chords progress though the measures, but because of randomness, is not always happening.
Have a listen to what I have suggested and see if it will work for you.
