"Changeup" is an album by Joan Jett, an iconic rock singer, songwriter, and musician. However, as of my knowledge capabilities up to September 2021, I couldn't find any record or mention of an album specifically titled "Changeup" by Joan Jett. It could be that the name is mistaken or it's a less-known release.
Joan Jett is well-known for her work with Joan Jett & the Blackhearts, including their hit record "I Love Rock 'n Roll", which was a number-one hit in the United States. Jett's other albums such as "Bad Reputation", "I Love Rock 'n Roll", and "Up Your Alley" have left a significant impact on the rock genre.
If "Changeup" is a mix or performance, or a lesser-known piece of work, further information might be challenging to find. Joan Jett's musical career spans several decades, characterized by her distinct rock and punk aesthetic. Her groundbreaking work in the male-dominated rock industry of the '70s and '80s cemented her status as the Queen of Rock 'n Roll.
In any case, it's always stimulating to delve into the topic of Joan Jett, as her influence on rock music remains substantial.
