Five songs is where a release stops being a collection and starts being a record. The tracklist matters, the sequencing matters, and the artwork has to hold across a front cover, a back cover and every promo asset.
Twelve hours is a little over two hours a song, which works when the material is ready. It's why we talk first — if two of the five are still being written, we'd rather plan for that than discover it in session four.
Back cover and tracklist design is included here and nowhere else, because this is the tier where people start pressing physical copies. If you're going to vinyl or CD, tell us early so we export to the right specs from the start.
