Ubuntu YouTube music player with playlist search and download

Question

I want to play YouTube music without having to run a web browser.

Requirements:

• Let me enter keywords to search for playlists, and select a playlist to play
• Let me easily download or at least bookmark tracks I like. I have Youtube-dl installed if that can help.
• Does not display video
• Free

Bonus:

• Runs as an Ubuntu indicator
• Open source
• Audio-only YouTube download, to save bandwidth (if possible)

Answer 1

mps-youtube is a console-based youtube player with playlist support. Doesn't display video, great for listening to music. It supports downloading media from youtube (although youtube-dl is much more full-featured regarding downloads).

You may also have a look at minitube which is a standalone (graphical) youtube player tring to match a TV-like experience.
