doesn't matter. you can't hear the difference.

And
that Android file manager will tell you the device can only be used to
store or transfer "flac" and "wav" files, when the default player gladly
renders beautiful sound when fed these massive files. It must be a deal
with Microsoft or something. "flac" is open source. MP3 is not.

whether something is open source or not has nothing whatsoever to do
with how it sounds.

in a double-blind test, you won't be able to tell which is which.
