I find just listening to the songs I enjoy (not necessarily upbeat in nature) really helps with my motivation. When my awesome uncle got me a boombox for Christmas I immediately made a playlist. When you're listening to music you love, time just seems to pass so much faster while undertaking tasks that would be otherwise tedious.
The songs in my playlist were:
Tiny Dancer (Elton John)
Piano Man (Billie Joel)
Waterloo Sunset (The Kinks)
Sunny Afternoon (The Kinks)
Swim and Sleep (Unknown Mortal Orchestra)
Blackbird (The Beatles)
Let It Be (The Beatles)
Eleanor Rigby (The Beatles)
For No One (The Beatles)
Instant Karma (John Lennon)
Californication (Red Hot Chili Peppers)
Breaking the Girl (Red Hot Chili Peppers)
Mr. Blue Sky (Electric Light Orchestra)
You Gave Me The Answer (Paul McCartney & Wings)
Listen To What The Man Said (Paul McCartney & Wings)
Magneto and Titanium Man (Paul McCartney & Wings)
Venus and Mars (Paul McCartney & Wings)
