Cassette - Long

Community servers often have a player who runs a radio: a boom box streaming music in a town or a market, with a station jingle in between. Thirty seconds is the most any cassette holds, so the jingle goes on this one, or an ad that lists everything your shop sells.

Record it on the cassette recorder and put the tape in the boom box. Hook connected speakers up to it and each one plays the same audio, so one tape covers a whole compound.

Of the three tapes it costs the most metal fragments and comes out one per craft, no bench needed. A recycler gives back a fair share, so an old tape is not lost. For a single raid taunt it is overkill.
