Drive for hours in the car listening to one or two songs on repeat. My car has an amazing stereo (I will go without food to have excellent stereo’s), which I bought while hypomanic last year. Although it ate a massive chunk out of my savings (it had to be the best of course) I am thankful for that hypomanic episode. I also am very animated while driving and sing loudly. I even slightly vear the wheels in time to the music. When stable I am mad about good music. When hypo/manic it goes stratospheric.
