Type in the Search box and iReal Pro matches on the song title or the composer, across everything you have downloaded, created, or edited.

 

A song that lives in more than one playlist lists each of them, so you can load it from a particular playlist, with that playlist's key and settings, or from the main library. On Mac and Windows, recent searches are remembered.
