What do you set up before releasing a project?

I’ve made Suno songs for fun, but I’ve never really tried to release them as a proper project. Now I have around 20 tracks I’d like to release more seriously, and I’ve been making cover images, grouping similar songs into playlists, and thinking about whether they should have a loose theme so they feel less like random uploads. For a couple of the stronger tracks, I also made short mood clips in Kling and SondoAI to give them a more consistent visual mood.

What do you usually set up before releasing a project? Playlists, a visual identity, a series of cover images, recurring sound motifs, or something else?
