Rock or Pop is a Field Bureau + Werkstatt project.

A playlist is a list. A mixtape was an object — choosing the order, writing the label, picking the shell. Rock or Pop puts the object back: paste a YouTube playlist and it becomes a cassette you can choose the cover, colour, and background for, and write a label on.

The whole tape is described by its own link, so there is no account and nothing to save. Send the URL and the other person gets your cassette, exactly as you made it.
