  • EDITING: crop, resize, rotate, drag and drop images, color adjustments, multi page TIFF export, and more.

Cantata 1.4

Cantata, a (yet another) client for the music player daemon (MPD), just reached v1.4 with new features and many improvements.

Cantata started off as a fork of QtMPC, mainly to provide better KDE integration – by using KDE libraries/classes wherever possible. However, the code (and user interface) is now very different to that of QtMPC, and both KDE and Qt (Linux) builds have the same feature set.


  • Library – sorted as Album Artist (or Artist if Album Artist not set), Album, and finally Track.
  • Albums – displays albums as icons, sorted by their title.
  • Folders – displays MPDs virtual filesystem. (This view is hidden by default)
  • Playlists
  • Dynamic – dynamic playlists
  • Streams – allows saving of internet radio URLs, searching for stations via TuneIn or ShoutCast, station listings from; Digitally Imported (+Sky, JazzRadio, RockRadio), TuneIn, IceCast, ShoutCast, SomaFM, etc.
  • Online – Jamendo, Magnatune, SoundCloud, and Podcasts
  • Devices – enables copying from/to USB-Mass-Storage (UMS) and MTP devices, and ripping AudioCDs
  • The sidebar has a context menu, allowing you to control its style and what items are shown.

  • Use MusicBrainz AlbumId (if set) to differentiate albums. This helps if you have multiple releases of the same album.
