The keyboard line you hear was actually played with a guitar, but I don’t have a guitar and the “guitar” sound the keyboard makes is nowhere close to the real song’s sound. Or a guitar’s sound. The place where it jumps from C♯4 to B4 and after there might be played by a string section.
There are no lyrics. It was purely instrumental.
Thanks for trying! In case anyone else cares to comment, it’s neither of these.
Its actually really bothering me I swear I’ve heard the tune before
