I was listening to some songs by the band Hatebreed and two songs have kind of profoundly positive lyrics:

If you want to make a difference in the world it means
You have to be different from the world you see

If you think you should judge someone
Start with yourself
If you want to take control
Start with yourself
Something you see needs respect
Start with yourself
And if you want to change the world, you have to
(Start with yourself)
If this vein of music is to your liking, you should check out some of August Burns Red’s Lyrics, they’re also typically very positive, and deal with a range of issues. A few that come to mind:
Their motto is angry music for happy people, and they really do kind of embody that HEAVY music with uplifting lyrics energy.
