Making one
A deck rises along the bottom of the store, and stays there while you browse.

The name field opens on the last tape you made — usually the one you're still filling. The name is what decides. Leave it as it is and these songs join that tape; type one you haven't used and you get a new one.

The menu is the same choice without the typing: take a tape off the shelf, or start a fresh one.
Open the count and the pile comes up.

Drag them into the order you want — they don't have to stay in the order the record had them. Then Record. Or discard it, which asks first.
