I-IV-V-I is the progression of so many pop songs, I-III-V is also a very common progression.
The biggest thing about pop is repetition. The idea that you want something repeated until it is in the listeners head, and also give them a direction they want to go so they think they know it. This makes them feel special.
As for drum beats todays pop has a lot of house inspiration so 4x4 is optimal unless its hip hop make 808s that change pitch and triplet 16 high hats.
This follows a 4x4 formula but the mix puts the elements so that it feels like it moves, but truthfully people hate really dissonant music so dont be too daring if you are a radio man. Just tempt them a little. This song is fairly simple follows the same prog and a 4x4.
You want pop music compose in major keys, 4x4, side chain the bass, fat kick, and make a progression people have heard so many times they feel they know it.
You want to switch it up to hip hop 808 and tune it so it shifts notes, 16 triplets, 32 triplets, 32s, and 8 triplets are acceptable for high hats, snare should always be on the second beat on both house inspired pop and hip hop pop. Have a repetitive but catch arpeggio, and have a bass that is almost worm like.
You a sampler? Sample some mello guitar, jazz song, dusty drum, or something else that makes people have that old school vibe and you've done it radio. boring.
