I have had Apple Music since about 1 hour after it was first pushed out 30 June 2015. To be sure it is a vastly improved service from what it started with. But I still have real problems with its search engine. I have real off the wall tastes in music, as Apple Music library has grown this is getting less and less of a problem. But I still have surprises. The track or album is usually there but somehow the name of the artist or album even when typed in correctly does not show up. I have to go outside to Google and input it there and it will come up in the choices of where to listen to it. I typed in SKÁLD as an example. It is OK in Apple Music but you can see what a Google search does. So if you can't find it using Apple Music's search engine just go outside to Google.
