Hi Thomas,

thanks for your report.
I could confirm it with 2.17.96.

Seems the default for baseline-skip isn't available while calling any
column-markup-command in the lists for repeatCommands.

A quick fix would be to change the baseline-skip-properties in those
commands to:
 #:properties ((baseline-skip 3))
I don't know if a better fix could be integrated in
repeat-acknowledge-engraver.cc, that's beyond my expertise.

A workaround for your example would be to explecitely declare the baseline-skip:

\version "2.16.0"

voltaToNextSong =
  \markup \override #'(baseline-skip . 1)
  {
        \text
        \column { "to go to" "next song" }
  }
voltaToFinish =
  \markup {\text "to finish"}

\relative c'' {
        \set Score.repeatCommands =
            #'(start-repeat)
        b1
        \set Score.repeatCommands =
            #(list (list 'volta voltaToFinish))
        b
        \set Score.repeatCommands =
            #(list 'end-repeat (list 'volta #f) (list 'volta voltaToNextSong))
        b
        \set Score.repeatCommands =
          #'((volta #f))
}


HTH,
