[Geoff Bacon]

Type some part of the song name, the artist name or required genre into the filter.
This will restrict the display to songs that contain the data in any part of metadata (not just the song title).
Select the required song (scroll if required)
Possibly select any other songs with same filter (you can position them once the setlist has enough songs)
Clear the filter and repeat for the other songs.

If you know the start of a required song name, you can long press the first letter in the alphabetical list (right edge on my tablet).
Then press the next letter in the name etc.

You can use a mix of these methods and those given by others
