You need to declare in your AndroidManifest that your app can handle these types of files. You do this with an intent-filter:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:scheme="content"/>
    <data android:scheme="file"/>
    <data android:mimeType="audio/*"/>
</intent-filter>

This means that any time an app launches an implicit Intent to play an audio file, your app will show up on the list of selectable apps.
