Pop is ALL about crafting the song (strong hook, clear singing, understandable lyrics). Prog is more about making it interesting musically (odd/changing time signatures, chromatic harmonies, complex lyrical topics). Rarely are bands good at bringing the two together. Also, it's totally normal for pop songs to be in 6/8 or even have the bridge and/or chorus in 6/8 and the rest of the song in 4/4.
