Hello, nothing you'd have to apologize for.
I mean I'm not a lawyer but what I've read about CC and how I took timings of sections of your music and integrated those into my code to sync dancers, etc. sounds a lot like what they describe as a derivative work.
Anyhow, I didn't expect an instant response like this let alone you actually changing the license. You're my hero of the day. Thank you kindly :)
I know 13.37 is but a small token of appreciation but still hope it gets you a tiny step closer to your Kpop singer :)
