Yes! To "think back" on something means to remember, recall, or recollect that thing. The line "I've been thinking back on you and I" describes the singer's actions of recollecting the memories she shared with her past lover. You can use this expression in other informal contexts to express a similar idea. Ex: When I think back on my childhood memories, I realize it was full of happiness and laughter. Ex: As people get older, we tend to spend more time thinking back on our past.
