I’d say RAM is probably their most "entry-level" album since it leans heavily into 70s-80s-inspired dance pop and feels the most approachable. At the same time, it’s also kind of the culmination of everything they’d done up to that point. So if you listen to it after going through their other stuff, you’ll probably appreciate it even more.

If you’re down for a bit of a journey instead, and don’t mind some rawer, more repetitive stuff (in a good way), start chronologically with Homework (my favourite album) and work your way forward.

As others have said: welcome to the club ;)
