If you search your library right now you can add individual tracks to the queue by long pressing, then selecting "Enqueue". However, what I am looking for is an easy way to search and then add all of the search results to the queue. The use case is this: I am assembling a queue, generally fairly long, for a working session. A number of the albums I have purchased have extremely large track counts. "99 Essential ...", "50 greatest...", etc. Very frequently, these have large subsections that could have formed a whole on their own. This is especially true with classical music where multiple distinct works are mixed onto one "album" and I want to select a single work. So, I search for the name of the work and the selection of tracks come up and I want to grab the whole set and append them to the queue without grabbing each track manually or putting the entire album onto the queue.
