This is my favourite album from what I've listened to from them so far, it's also the only thing I have on bandcamp :D

I never heard about BandCamp, thanks for the presentation and giveaways!

I don't know of any nice Bandcamp albums, but I voted "Other" in the poll. I use the website di.fm for when I don't have anything in particular to listen to. It's an internet radio for various electronic music genres, like trance, house, techno, etc.

Here's some of the bands (and songs) that I listen, unfortunately it doesn't meet your criteria but maybe you'll find it interesting:

• Oingo Boingo (Just Another Day, Grey Matter, Insanity)
• Morrissey/ The Smiths (Spent the Day in Bed/ What Difference Does It Make?)
• Siouxsie And The Banshees (Spellbound, Cities in Dust)
• Sisters of Mercy (This Corrosion, Dominion Mother Russia)
• Marilyn Manson (No Reflection, Eat Me Drink Me, Saturnalia, The Mephistopheles Of Los Angeles)
• Eyes Of the Nightmare Jungle (Shadow Dance)
  There are also The Cure, The Cult, Fancy, Enya, KISS, HIM and many more but I don't want to wirte an essay. Maybe you'll find something for you (but I doubt xp).
  Edit: I forgot that it has to be available through Bandcamp, but some of these surely will be there. I don't use Bandcamp at all. Sorry. :P

bump, I not used bandcamp services yet

off the top of my head:

Could be uplifting[+electronic]:
https://analogicalforce.bandcamp.com
(dropping an entire label as recommendation because really it's all gonna be up your alley if even one album hits)
uplifting,electronic,chiptune-y:
https://ceephax.bandcamp.com
uplifting,electronic(entire discography really,not just this one):
https://jonhopkins.bandcamp.com/album/immunity
background:
https://starsofthelid.bandcamp.com
possibly uplifting,electronic:
https://timhecker.bandcamp.com/album/an-imaginary-country

Many video game composers are on bandcamp so you got quite a few choices for your uplifting chiptunes btw.

Took me a while to find something I love which is also featured on Bandcamp, but here we are:

https://emancipator.bandcamp.com/album/safe-in-the-steep-cliffs

It's electronic music, which is bright and uplifting (if more on the deep side of things) and also works well as background music I suppose. Let me know if you liked it :)
Edit: I use Deezer as my primary online streaming service.

https://au5music.bandcamp.com godlike edm here

https://vvidovv.bandcamp.com/releases kinda folk, kinda electronic, but really awesome, if you can search for the rest of his songs on other place, a personal recommendation, Windswept

https://thelucksmiths.bandcamp.com/album/warmer-corners
One of my favorite bands. Sunlight in a Jar is my favorite. Bright and uplifting and some vocal harmonies.

Maxthor
https://maxthor.bandcamp.com/

Stand out tracks from the album Another World are "Howlings In The Night", "Set Your Wheels On Fire" and "Hunters"

https://maxthor.bandcamp.com/track/howlings-in-the-night
https://maxthor.bandcamp.com/track/set-your-wheels-on-fire
https://maxthor.bandcamp.com/track/hunters

And standout tracks from the album Fiction are "No One's Gonna Save Us", "Run", and "Crossing The Line".

(If you're looking to Bandcamp specifically to give financial support to the artists you're interested in, keep in mind that they're doing another Bandcamp Friday on the 7th. Bandcamp waives all their revenue share so all proceeds go straight to the artist(s) you buy from on that day.)

Most outright electronic stuff I listen to checks your "works great as background music for reading/falling asleep," but it's mainly dark ambient stuff that's more unnerving than it is uplifting. Some psybient and video gamey stuff might work, so check these out:

https://ottsonic.bandcamp.com/track/the-queen-of-all-everything
https://entheogenic-usr.bandcamp.com/track/pagan-dream-machine-vibrasphere-remix
https://sheofficial.bandcamp.com/track/coloris-2
https://zirconstudios.bandcamp.com/album/unearthed

For something way out of your wheelhouse that nevertheless checks a couple of your boxes (vocal harmonies; bright and uplifting), try Spanish prog rock group Cheeto's Magazine. Although a rock band, they have two lead keyboardists, and their approach is about as a fun-loving and light-hearted as it comes. I'm obnoxiously elitist about this type of music and usually can't stand when bands inject their haha-so-funny-and-random humor into it, but the actual songwriting and musicianship here is so high quality--and the silliness is evened up by a kind of heartfelt earnestness that somehow makes the humor work for me--that it might have been my favorite album of 2020. And I listened to hundreds of 2020 albums. @_@ Anyways, check it out: https://cheetosmagazine.bandcamp.com/track/big-boy

I'm currently the sole Soundcloud user in the poll, but that might be because I tend to seek out individual remixes, rather than stream playlists. :P

Genres are sometimes a bit nebulous, but maybe you might like some melodic EDM from Illenium or Seven Lions?
https://illeniumashes.bandcamp.com/album/ashes
https://seekingsevenlions.bandcamp.com/

I fell in love with Bandcamp the moment I discovered it 7 years ago or so, such a huge variety of high quality music. I especially love the Bandcamp Weekly show, it's a great way to keep up with and discover the artists and music on the website.
I'm not sure that I can think of an album that meets your criteria but feel free to check my small library: https://bandcamp.com/kaiser_ali

Bumf

Thanks for all the recommendations everyone. Keep them coming! I'm going to have quite the Bandcamp Friday this week!

I also added a 2nd batch of giveaways to the main post to thank everyone for contributing so far.

Only searched for one of my favourite bands, but apparently they have 2 songs up on bandcamp! Which was surprising, considering that they barely have any songs out on any digital platforms
So here goes:
nekomusume - 染まる日
nekomusume - sora!

Kingdom (Classic) OST

Ozric Tentacles is everything of that in one band
Here's one song:

I mostly listen to music live (though not at the moment sad), or on the radio in the car.
