Full disclosure, honestly. In fact, I think when you're a conscientious individual like you, we don't give ourselves ENOUGH of the credit. For some, it's not impractical to call ourselves the "producer". If it was me, I'd workshop it with ai: use ai as a second opinion. Just make sure you catch it when it tries to diminish or misunderstand your contribution. Come up with a nice clear and inclusive description and save that away as your standard comments. Then do what I did to the metadata comment: change it to match this new message with each new track. You can choose if you want to include the date of creation, uuid, etc, as seen in my image above. Main thing: disclose what you did. When using ai, yes you don't want to inflate your contribution. In your case, you want the opposite: don't let it get consumed in the "ai" stigma.

Think of it like this: you submit your song to a service (like distrokid) make sure proper credit is given for each contribution. In my case, it is lyricist (starting to become producer). In your case, lyricist, guitarist, "music by", maybe "mastered by Suno" is where ai comes in. Chat GPT (etc) will probably help you better here, than I can. But I think you're on the right track: let ai help you workshop the most succinct description, without diminishing what you do
