Keep in mind that playing the E for an A/E chart is typically a guitar based chord chart. A lot of keyboard based music is written this way as well, but it relates to "Left hand/right hand". In this case the note or chord on the left is the bass, not the right. This doesn’t happen a lot because typically the music is standard score sheet music or guitar chord charts. But once in a while you will see the keyboard based charts with the left/right thing, so just keep that exception in mind.
