Yes, the Nemesis music is still played in the Queueline aswell as the Station and around Forbidden Valley, obviously excluding the Air area. The soundtrack was changed temporarily in 2007, in which a more generic and less melodic track was played that was less comprehensible from the queueline, muchly due to relying heavily on the Station's bass cannons. In October 2007 the original music returned to the entire area with much applause.
However, the full soundtrack is no longer played which includes the Nemesis story and an extended mix of ambient sounds, as well as the main Soundtrack looping 4 times. This went out a long time ago and was relpaced by a 3 part loop of the main soundtrack, with the story cut. Since the 2007/8 relaunch the park only have a sample version which contains a single loop of the main soundtrack, which cuts out 15 seconds are so from the end when it would usually flow back into the main melody.
Hope that helps :D
