I recommend
Afropop (from Nigeria, Ghana, and Kenya) for consistently good, catchy pop music. It's a lot better than most popular music today, and better yet a lot of the songs have really nice, meaningful messages about love, marriage, helping others etc. There is some music that isn't good, but a lot of very catchy songs.
P-Square, Sauti Sol, Iyanya, Don Jazzy, Reekado Banks, Sound Sultan, Ice Prince Zamani and Dr. Sid are just a few of the many good singers (all Nigerian, except Sauti Sol). I could name more, but will stop there
Most of the music is in (Pidgin) English, although there are often Yoruba, Swahili, & Igbo lyrics too, which is fun to learn
Romantic Reggaeton is often pop-ish, and there is
Kpop too (although I personally think it's gone downhill since a few years ago
). There are also some good
Arabic language pop
-ish singers, although they aren't generally from consistent countries (Maher Zain and Humood Alkhudher are my favorites although Harris J is like the Muslim Justin Beiber lol
The lyrics are usually very nice too!).
