Any suggestions on how to add music to a timelapse video? I am using lightroom 5 and Lrtimelapse 3. Any help would be great. Thanks

You will need to use a video editing program to combine different sequences rendered with LRTimelapse and add music.
A good choice for beginners is for example Adobe Premiere Elements.

You can also do it in Quicktime, though possibly only the Pro version.
