That’s kinda non-trivial.
For a start, if you want to use OSC, then you’d like your OSC app to be able to display the current list of songs (say) and you really need to use something sophisticated that supports that kind of thing. See for example
A simpler approach might be an app that can just send MIDI Program Change messages. You would still need to know the PC numbers for each song. Maybe something like MIDI Commander on Android. (NB – I just looked that up - it seems like it might do the job but I don’t use android and so I have not tried it myself so can’t guarantee that it would work)
