A "comeback album" refers to a music album released by an artist or band after a significant period of absence from the music scene. This absence can be due to various reasons, such as personal issues, changes in the music industry, or a hiatus from performing. The album often aims to re-establish the artist's presence and reconnect with their audience. These albums can be crucial for reviving an artist's career and may feature new sounds or styles that reflect their growth during the break. Notable examples include Madonna's "Confessions on a Dance Floor" and Fleetwood Mac's "Say You Will," both of which marked significant returns to the music industry.
