(Download Happy Music by The Blackbyrds at Mediafire)
The Internet doesn't have the full lyrics anywhere- so I will supply the missing lyrics which are relevant for our purposes:
" when you get up/and you gotta / start your day
feelin' lazy/and confused / you can find your way
Happy music/is the music / you need to play
if you want to/it will help you / save your day "
Good thing I am not writing my dissertation right now, because today, and the days that are like, have been and will be like, today, even preparing for class seems a chore.
Confused and Lazy.
Happy Music, sure, but also pretty dark for this band. Sort of the inverse of a point I've made before: The Stooges' "No Fun" is actually probably their most fun song.

For the Blackbyrds (most of their songs are fun, and light 'n' mellow),
this actually has a pretty dark edge.

Now, dark and happy are not strictly opposed- but neither do they have any necessary connection.
You could be both dark and happy at one moment, but that would be a bit of the old "cake and eat it too," wouldn't it?

So certainly these days (late-year, ... etc. ...) are dark, but ideally, they would be happy, for you, as well.
