01 / THE PLAYER

Just enough, beautifully contained.

01

Find a track. Or bring a URL.

Search by song, artist or playlist, or paste a YouTube video or playlist URL into the player.

02

Keep bookmarks, not a media library.

Save URL bookmarks and return to them later. M³ is an audio streaming and URL bookmarking player, not a downloader, editor or media redistribution application.

03

A smaller place on your desktop.

Switch to Mini for a compact control bar, with playback, volume and saved-link controls close at hand.

02 / WINDOWS CANDIDATE

A careful first listen.
