Then download a simple audio editing app to trim the song to 30 seconds. Again, there are hundreds of free ones available (your phone might already have one installed).
If you're just playing the first 30 seconds of the song (rather than a specific section), you don't even have to do that.
Almost all sound systems should have bluetooth or even a wired connection so that you can then play them during the quiz.
Might sound like a faff on the surface but it's far more efficient (and cheaper!) than the "old school" way.
