I've seen this at the Aldi stores near me here in the Northeast US

I've had some success using moOode audio on a Raspberry Pi (included in the Pi Installer I think, but here's their website in case I'm misremembering). I use it with Roon, which is linked to my streaming service and allows me to stream tracks; but I see it works with Spotify Connect too, so if that's your service of choice then perhaps this will work for you!
