Gamp

Drop music files or a Winamp skin (.wsz) anywhere on the page. Your music never leaves your computer: nothing is uploaded or stored anywhere, it plays right here in the browser. Keys: Z back, X play, C pause, V stop, B next, L add. Click G-Drop for the next preset; the V on the main window hides or shows it.
SoundCloud, Spotify, Plex, your NAS, internet radio, the music library and full-screen G-Drop are in the desktop app for Mac and Windows. Skins from the Winamp Skin Museum.
