nostr:npub1y0qtcnudw0u3zgucuuzc96yt4jrwm6ejlwjarg3t7pnz8c0ftvvq6twrne specifically for the services you mentioned, I've migrated from Dropbox to Nextcloud a while ago and haven't looked back. And from YT Music to Tidal - it's definitely far from ideal, they don't even have a Linux app, but they have an unofficial web API that so far they haven't bothered to switch off, and it works great with mopidy through the mopidy-tidal extension (which I also contribute to).
