YES! Those are the kind of jams I listen to. Positive up lifting music. Though, my tastes lean more towards the rock side so it might be too rock for you. Here they are anyways
Melodysheep on youtube has some of my favorite autotune tributes of inspirational people like Robin Williams, Charlie Chaplin, Bob Ross, Mr Rogers.
Anything by the Aquabats is just happy slappy fun music about how if you're working hard you're a winner
And one last place I turn to for positive rock is 106.3 The Rock radio station (it's Christian station but very decent rock Skillet, Flyleaf, Demon Hunters,TFK, Amberlin)
A bit of Classic Rock, Slade has a lot of fun music and songs about raising out of the dark depressing times.
BNL cover of Lovers in a Dangerous Time has one of my favorite lines of all time, "Kick at the darkness till it bleeds daylight" <3
Then there's Weird Al, Slade, NSP, lots of ska bands. I love the positive beats XD
