Buy a licence and download. A licence is not a transfer — the seller keeps the file and can license it to anyone else, so there is no scarcity and no resale.
Listing costs 1 TCC per 30 days, paid up front. Unsold listings expire and are cleaned up; anything with at least one licence sold is kept for good, because someone paid for it.
Everything you have listed, with what it has earned.
Built from the on-chain listing records — revenue is licences sold × price. It counts what is listed now, so an expired listing drops off.
