Amazon’s Prime Music? Most people have prime anyway, I think that comes with the ad version. Less than Spotify to switch to add free.
If you still have access to any .edu email addresses, you can get student rates for Apple Music, and probably others.
No addons that I know of, but they do an annoying thing where they change which specific version/release/album of a song is available, so your playlists end up missing songs even though the song itself is still available and you have to correct the playlist.
