I believe the answer is:
ipod
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">touch for one</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for ipod that I've seen before include "Music player" , "listening device" , "Familiar gadget" , "Pocket-sized device for playing music" , "Brand of portable digital media player" .)
