Final answer:
The early songs of the Rolling Stones were primarily influenced by blues, which contributed to the sound and success of rock and roll music in their era.
Step-by-step explanation:
The early songs in the Rolling Stones' career were primarily influenced by blues music. The combination of electric instruments with the sounds of gospel, blues, country, jazz, and R&B gave birth to the new sound of rock and roll, a genre that captivated a wide audience, particularly teenagers. This is exemplified by the various styles that were emerging during that time, such as Chuck Berry's rock and roll that dazzled crowds and fused rhythm and blues with the rock and roll sound, and Bill Haley and His Comets' rock and roll anthem "Rock Around the Clock." While the Rolling Stones were influenced by many genres, blues was the primary foundation of their early work, setting the stage for their impact on rock and roll.
