I have never used it, but from what I understand it can stream from a bunch of online services (mainly through plugins). YouTube and SoundCloud, for example, would be the most useful in my opinion.
This software requires a large number of Qt4 libraries, which aren't currently provided by Solus. So it's gonna be a while, if ever.
Either the Qt4 dependencies will need to be provided, or the upstream will need to port to Qt5.
I would recommend moving this to either low priority or wishlist.
