Very cool, but tried pasting a few playlists and it never fetched more than 95/98 tracks (playlist had 100+ tracks in it). I'd be interested in the open source version, so I could run it locally on cron.
the self-hosted version has been improved a lot recently — works out of the box with zero config now. flac requires deezer or tidal credentials for now, but i'm working on a proxy solution so self-hosters can get lossless without needing their own subscriptions.
