Suggestions welcome: replacement for music buying + voice-activated speaker

For the longest time I've been buying digital music from Amazon and then playing it with voice activation on my Amazon Echo while I work in the kitchen.

I want to migrate this process to a new European-based platform(s). But I want to keep buying digital music to more-directly support artists (as opposed to giving money to Spotify), and the voice-activation is pretty essential while I'm in the kitchen working away.

Could someone please give some suggestions of what platform to buy music from, in combination with what voice-activated speakers I could use? I don't mind introducing an extra step if I have to, e.g. buying mp3s and then manually uploading them to a repository somewhere else.
