Toast, how do you define soul?
My definition of soul is strongly similar to what I think one might define consciousness: what it feels like to be something. However, one might pare it down so that it's more that there's a level of awareness enough to give a capacity for experience, unique to that entity. The capacity to have that feeling (which is an experience). In some ways, it may sound a lot like Atman.
Of course, this leaves the concept very permeable to explanations yet to be discovered or even a new way of thinking of ones we may already have. It could be on a spectrum of epiphenomena, panpsychism or even idealism. This definition also leaves open the question of how much identity and self-hood (to be distinct from the idea of The Self) contribute to more common ideas of the soul, which I think matters a lot to people for matters of history, uniqueness and importance for moral behavior. This definition also doesn't necessarily conflate with other topics like free will and agency, and their consequences. However, the soul and its definition might be important when weighing those matters.
While it is important to discover explanations and do the research, if we're not even sure what we're looking for and how it matters to us, its salience is lost. The soul is not "real" in the sense that love or happiness isn't "real". They could all "just" be electrochemical processes and hormones, which on the aggregate give us a set of phenomena which matters to us, having import to how we live and think about our lives and the world in which we do it. Call it whatever you want, what might be more important is that we find something to agree about. Using "soul" to refer to it can be reduced to data compression, if you wish, for the sake of communication.
