第一段：

$puts(track.w,$gettextwidth($get(track.text)))
$puts(title.w,$gettextwidth($get(title.text)))

$if(%bpm%,
   $puts(bpm.text,%bpm% BPM)
   $if(%tracknumber%,

第二段：

$puts(artist.text,[ / %track artist%])
$puts(title.text,%title%)
$puts(title.w,$gettextwidth($get(title.text)))

第三段：

本来以为今天一下午能弄完，现在一拖又是三天
