Further, Spotify premium allows you to skip songs as much as you'd like - without the cap that the free version limits you to.
While this is a small feature, this is crucial for people who have premium headphones or speakers. If you pay for the premium service, this also allows you to bump up the quality of audio that plays - which is set at 160kbs on the standard player but can be increased to 320kbs when the premium is paid for. The player also includes a lot of non-music extras, per se, such as podcasts, speeches, and lectures. It plays a variety of artists and musicians and you have the ability to pay for the service, which will remove the ads that are embedded.
The software is like all other music-playing apps that are online right now.
