#So this is a simple mp3 player I'm trying to make on python/kivy. I'm using FileListView to display my mp3 files. Is there a way I could select a song from the FileListView (by click), load it to the Soundloader and play it with the PLAY button?#

#so the question is how can I actually combine the Filelistview and the Soundloader modules so that I can click on a song from the list and play it instantly?
A few modifications gets your code working. First, your binding of the filechooser selection should use the property name, like ths:
flc.bind(selection=self.load_sound)
Then, making an instance variable to hold the sound makes it simpler to handle. Here is a modified version of your code with those changes:
