The Runaways broke up primarily due to personal conflicts, creative differences, and the pressures of fame. As the members grew older, they sought different artistic directions and faced challenges in their relationships, particularly between Joan Jett and Cherie Currie. Additionally, issues with management and the demanding lifestyle of touring contributed to the band's dissolution. Ultimately, after their final tour in 1978, the members decided to go their separate ways to pursue individual careers.

The Runaways, a pioneering all-girl rock band from the 1970s, consisted of five key members: 1. **Joan Jett** - Rhythm guitarist and vocalist, known for her later solo career. 2. **Lita Ford** - Lead guitarist, recognized for her heavy metal influence and solo work. 3. **Cherie Currie** - Lead vocalist, known for her distinctive voice and stage presence. 4. **Jackie Fox** - Bassist, who contributed to the band's sound before leaving in 1977. 5. **Sandy West** - Drummer and co-founder, celebrated for her powerful drumming style. Together, they helped shape rock music and opened doors for female musicians.

Joan Jett was 15 years old when she joined The Runaways in 1975. The band was formed when she was a teenager, and it played a significant role in her early career in rock music. The Runaways gained popularity in the mid-1970s and became one of the first all-female rock bands to achieve commercial success. The movie "The Runaways," released in 2010, chronicles the band's rise and the experiences of its members, including Jett, who was portrayed by Kristen Stewart.

The Runaways' biggest hit is widely considered to be "Cherry Bomb." Released in 1976, the song showcased the band's blend of hard rock and punk influences and became an anthem for teenage rebellion. It features catchy lyrics and a memorable chorus, helping to establish The Runaways as one of the pioneering all-girl rock bands of their time. The song has since been covered by various artists and remains iconic in rock music history.
