tl;dr: Fastpotify is a lightweight native Spotify client for Linux, macOS, and Windows that starts in under a second, supports local gapless playback up to 320 kbps, and integrates Spotify Connect for controlling remote devices. It offers library browsing, search, playlist editing, keyboard shortcuts, MPRIS media controls on Linux, and a system tray option. It can also load classic Winamp .wsz skins from the Winamp Skin Museum, turning into a period-accurate mini player with analyzer, equalizer, and shade modes.
