Brown Eyed Girl

Currently listening to Pandora. It lets you create your own station based on a particular musician, and then plays songs from artists similar in nature.
Of the many stations I created, one was on Van Morrison, the song that first played was "Brown Eyed Girl". The next song that came up was "Not Fade Away" by The Rolling Stones. On querying the station, as to why it played this song the response was:
'Based on what you've told us so far, we're playing this track because it features mild rhythmic syncopation, repetitive melodic phrasing, extensive vamping, mixed acoustic and electric instrumentation and major key tonality.'
Hmm... I see.
