I wrote a song for my girlfriend this way. It turned out pretty nice. A bit quirky is not necessarily a bad thing when making personalized content.
Took me a couple of hours to get it to my liking, including learning all the tools and the workflow for the first time. And fixing up a couple of mispronunciations of her nickname using inpainting.
Overall a very productive environment, and will probably try to make some more songs - an replace the vocals with my own using the stems feature.
I have some audio engineering skills, dabbled in songwriting, guitar and singng when I was younger, but actually never completed a full song. So it is quite transformative from that perspective!
