Easy Windows App for Flac & AIFF for Novice


What's the best Windows app (free or cheap) for a low tech novice to use to play Flac & AIFF files? Good sound quality matters, but easy, intuitive setup and UX is top priority here for a non-hobbyist that would like to play some live recordings that I will share. Bluetooth speaker from the windows pc will be the playback method used.

Logitech Media Server works well I'm not sure how it compares to JRiver or Foobar I went from it right to the Auralic app.
@jaybe VLC is a great idea. I have used it for video but never thought of it for audio playback. 
FYI, UX is user experience. 
I totally agree with you about the weakness of bluetooth, but this isn't for me, it's for a friend who will only play via a bluetooth speaker, not a hifi system. Thank you. 

Thanks guys for the other suggestions, but "clunky" is the opposite of what I'm looking for here. Jriver is too costly, I saw there's a newer free "Jukebox" version...it has no images which seems basic and expected these days in any music app. 
LMS via Squeezebox was my go-to around 1995. From mentions here, I get the impression that it hasn't changed much this century, lol. Maybe that's plan B if VLC doesn't work out. Cheers,

Great UX experience and while not a Windows solution works really well controlled from a PC  Volumio and a Raspberry PI.

For under $50 with the power supply and the free version of Volumio It's an outstanding music server and an inexpensive way to share USB hard drives across a network.

Setup is pretty strait forward.  I'd still be using it if Amazon Music would have released the API
