Clever theme! I definitely know the song — and even could sing the chorus along — but quickly realized I didn’t know most of the lyrics, and I had never heard of the band. However, the grid pattern led me to fill in the circles.
The title also served as the seed of an earworm, and I thought I might like to listen to the song to manage this. But it looks like the band’s name is actually spelled STARECASE! Today I learned.
On a separate note, I loved the clue for 30A. Would just recommend adding a couple spaces for readability.
