Deja vu?

[Poxican]

I'm workin on something new but I can't help but think I've heard it before... it's maybe just from listening to it over and over. But then, it might be because it sounds too much like a song that already exists.

It's super rough just now, just getting ideas down, but I don't want to persist with it if it sounds too much like an existing song.
Would appreciate someone giving it a listen

[edit] just to emphasise, yes I know its shite at this point
