Someone on r/mandelaeffect has mentioned this song,
The Weeknd - Blinding Lights which was released at the start of this year, but which contains a very familiar keyboard bit, and I agree with them, it seems familiar to me too. Listen at 0:40-0:49 and 1:47-1:57. I'm sure I've heard it in adverts/background music/jingles type stuff going back years*, but just that keyboard part, not any of the rest of the song. Does anyone recognise what they've sampled/ripped it off from. It's something from around the 90's/early 2000's maybe?
And it's not from Take On Me or Young Turks. I can see why people suggest those but the keyboard bit I'm remembering is identical, not just vaguely similar, plus I don't listen to Radio 1 or anywhere that would've aired this song.
*Perhaps in one of those dance music compilation albums advertised on tv.
EDIT: Or has it featured in a lot of commercials this year, because I try to ignore commercials but it that little keyboard bit had featured in a lot of commercials really rammed down our throats ad nauseam I can see how it'd manage to worm it's way into my brain without me even noticing.
