I use a never-been-activated Android phone, $65 from Walmart, with the free version of Rocket Player Ap. I installed a 32 gig SD card. My backing tracks are MP3 files. I rename the files with numbers in front of the song name to create set lists.
Example
1-JustAnotherDayInParadise
2-BoatOnARiver
3-SweetViolets

This way they show up numerically in the order I intend.
I have another set list in alphabetical order so I can find a song quickly that way when needed.

I have a passive stereo volume pedal on the floor between the phone and the PA so I can fix any goofs quickly in case I start a song and realize I forgot to put my capo on.


Does the noise in your head bother me ?
