What would be the point in having the songs tab randomized? If you want to select a random song, you can tap the ? icon in the alphabet list to randomly select one. The reason it might make sense for a group type such as setlist or collection is that you might want to have a specific list of songs that you shuffle, but with the entire song list, I can't think of any good reason to do that because you can't load all of those songs at once like you can with a setlist.
