I don't know if it is the case with "It Don't Matter to Me," but Dial Global edits or pads numerous songs to make them fit into the time-sensitive local option breaks at the start of the hour, bottom of the hour and about 10 to the hour. One of the more noticeable ones is Billy Joel's "Don't Ask Me Why," which is padded to fit three minutes by extending the intro. Another blatant edit is Johnny Mathis' 2010 cover of "Shenandoah," which has about a full 90 seconds excised. That one runs just on the regular playlist, but was butchered from about 4 minutes down to 2:30.
