I don’t use RhythmBox or Banshee, as they are too bloated for me. I was a Winamp user.
I tried Audacious, DeadBeef, and Clementine. The following is a brief comparison,
|Shortcut key||Affect application only||Affect application only||Global hotkey|
|APE tag support||Didn’t test||Can load APE tag||Cannot load APE tag|
|AAC support||Correct file extension needed||Can play||Can play|
|Drag-and-drop songs among playlist||Copy||Move||Copy|
|Copy-paste songs among playlist (Ctrl+C and Ctrl+V)||Can||Cannot||Cannot|
Clementine global hotkey gives me trouble to navigate the audio file within the application.
DeadBeef works well, the only drawback is managing the playlist.
And, my favourite is Audacious. It works well in various aspects.
P/S: Just found that Audacious cannot customize the shortcut keys, but only the global hotkeys with the plugin enabled. The default shortcut keys are Winamp compatible.
