Final answer:
The industry referred to songs like Lloyd Price's "Good Lawdy Miss Clawdy" and The Penguin's "Earth Angel" as: crossover hits.
Step-by-step explanation:
Crossover hits are songs that achieve success not only in their original genre, in this case R&B, but also cross over to the more lucrative Pop market. These songs appeal to a wider audience beyond their primary genre and gain popularity in mainstream music.
Crossover hits often demonstrate the ability of an artist or song to transcend genre boundaries and appeal to a diverse range of listeners. They can contribute to increased commercial success and exposure for the artists involved.
In the case of "Good Lawdy Miss Clawdy" and "Earth Angel," their success in both the R&B and Pop markets made them notable examples of crossover hits.
