If you're coming from Crosshare, this puzzle's theme likely won't mean much to you, but hopefully you'll still find it solvable and maybe even enjoyable, especially if you're musically inclined! A brief explanation and links are provided in the comments.
Explanation: I run a twice-yearly online songwriting tournament called SpinTunes, and SpinTunes 20 is currently underway. Each tournament consists of four week-long rounds, during which participants must write and record a new song in response to that round's specific challenge.
Each of this puzzle's theme entries is the name of a band or artist who has been participating in SpinTunes 20.
