Q1: Why does Demus import only half the songs from my Spotify playlist?
A1: This happens due to metadata matching issues. Demus pulls song titles from Spotify and searches YouTube for audio streams. If an obscure track, acoustic session, or region-locked song lacks an exact, high-confidence match on YouTube, Demus discards the track to prevent playing the wrong audio file.
Q2: Do I need a Spotify Premium account to import music into Demus?
A2: No. Demus never reads your actual audio subscription status. It only looks at the public metadata of the playlist URL you provide. Free and Premium accounts share identical playlist URL structures.
Q3: Is using Demus to listen to Spotify music illegal?
A3: Demus does not copy or redistribute Spotify's copyrighted audio streams, which keeps the app from infringing directly on Spotify's audio rights. However, the app operates in a legal gray area regarding Spotify's Developer Terms of Service, which strictly forbid using its catalog metadata to operate rival streaming platforms.
Q4: Why does Demus say "Playlist Not Found" when the link works fine in my browser?
A4: This error usually occurs because the link includes tracking arguments (the `?si=` parameter) or the playlist is set to private. Make sure the playlist is marked public in Spotify's sharing settings and remove any tracking text following the main playlist ID before pasting.
