Good music is surely a mood enhancer.  We got some SONOS equipment years ago.  I have two of the One wireless speakers in my office space.  The SONOS app is amazing.  It brings in all your music sources in one place and you can control by phone, tablet and computer.  So my iTunes library, Spotify, Pandora, XMRadio, etc. are all together in the app.  You can create playlists mixing music sources also. We also have our home speakers connected to the system so we can listen throughout the house to the same music when going from room to room. Check out the details.  You won't be disappointed.  While we prefer a pair of these, even 1 by itself is amazing.  There are also larger speakers and portable ones.
