Sayonara is a small, clear and fast audio player for Linux written in C++, supported by the Qt framework. It uses GStreamer as audio backend. Sayonara is open source and uses the GPLv3 license. One of Sayonara's goals is intuitive and easy usablility. Currently, it is only available for Linux. Although Sayoanra can be considered as a lightweight player, it holds a lot of features in order to organize even big music collections.
Managing your library
You can manage your library by artists, albums, genres or file paths. Sayonara contains a sophisticated tag editor helping you to keep your collection clean. You can hold multiple playlists simultaneously, save/rename/delete or export them to common playlist file formats. There are even more complex library plugins like Soundcloud or SomaFM support.
Plugins
In addition, there are some useful plugins helping to enhance your comfort while listening. Some interisting plugins are the equalizer, a speed/pitch control, a crossfader, bookmarks for tracks and a broadcasting function.
Webstreams and Podcasts
You can record all tracks that are streamed from the internet and which are automatically tagged. When listening to ordinary webstreams, a history of all played tracks is displayed. If webstreams or podcasts contain some chapter information, Sayonara also uses this information in order to provide fast jumping within these tracks.
Conclusion
Most of those features are known from the more heavyweight and well known audio players. But in contrast to most of them the main focus during developing Sayonara has been performance, low CPU usage and low memory consumption. So Sayonara is a great alternative to players like Rhythmbox, Clementine or Amarok. Those who miss Winamp for Linux should give Sayonara a try. However, every user has special requirements and own habits, so it's always a matter of taste.
