mps sticks very close to mps-youtube in terms of operation and playback; enter a search term at the startup and mps will show a series of results. Cue the number of the track and mps feeds it into mplayer (or mpv), and the standard keys and controls are available to you.
The home page for mps suggests it can also create playlists, search for single tracks or through album lists, download tracks as well as stream, and a few other nifty tricks.
The home page also says the program works with python 2.7 and 3.3, but does not require any python dependencies. I’m a little fuzzy on that, but as a general rule of life, I subscribe to the principle that less dependencies is better.
I’ll keep this short since much of what mps does is similar to mps-youtube, and rehashing the features of one isn’t necessarily an endorsement of the other. If you liked the way mps-youtube worked — and I did, quite a lot as a matter of fact — mps is going to be familiar and enjoyable. Try one, try the other.😉
