Musictube is a YouTube music player. With it, you can listen to millions of songs on YouTube in a convenient way, much like using a traditional player. Musictube plays album tracks in their original order and integrates album covers, artist pictures, and lyrics.
Musictube can play full albums or even discographies of millions of artists present on YouTube. Besides listening to plain studio recordings, you can switch to "live mode" to listen (and watch) live performances, or to "cover mode" to discover surprising new versions.
Musictube has a fully editable playlist you can fill in seconds and let play for hours. You can always show the video as a thumbnail or full-window. Handy for official music videos, live performances, and covers.
Note: Although Finder indicates that this is version 2019.0730.111741, the developer states that this is version 1.8.1.
