Julius {l Wrote}:I don't think this additional provision is compatible with the CC-by license you state elsewhere.
Not necessarily, the first part could be compatible. The CC-BY license says:
You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
One could argue that "I must be listed, by the name Syndroversion, as a musician in your project’s credits" considered to be a "reasonable manner", however the license's wording suggests that the "how" is determined by the licensee, and not the licensor. Also, as you have pointed out, a game might not have an about box at all, so the second part is a non-sense, more on
this.
If in-game acknowledgement is really what the OP is after, then I suggest to use
GPL instead. It has some drawbacks, and being copyleft might introduce some additional problems too, but at least GPL mandates an in-game display of the copyright, just as the OP wanted (emphasis by me):
If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:
- {l Code}: {l Select All Code}
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different;
for a
GUI interface, you would use an “about box”.
But IMHO it would be better if the OP would allow their users to choose how the attribution is made, listing the copyright of their music along with the other attributions (however that's might be done).
Cheers,

EDIT: uh oh, CC is a real mess reading the
legal code. Section 3(a)(1).A.i "identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner
requested by the Licensor", but then, in Section 3(a)(2) "You may satisfy the conditions in Section 3(a)(1) in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material.", so I believe despite this contradiction the ultimate decision is on the licensee, and the licensor can only request "what" (how their name and the licensed work's title is written), but they cannot request "where" the attribution is made.
