If anyone is looking for music to listen, or just some funky beats that slap, Spotify seems finally realize how popular City Pop has become (and that Plastic Love isn’t the only city pop song that exists) and seems to have put a ton of stuff over the years. They finally have a lot of Anri’s stuff; basically the artist that got me into City Pop in the first place.
I find City Pop is a pretty good learning tool. Not only are they awesome, but they’re fairly slow and easy to understand. Highly recommend listening along with some lyrics to get your vocab in.
