Spotofo is your friendly collaborative playlist manager.
When you login to this service your currently playing track information is shown here and your plays are added to a collaborative playlist. And of course you can see what others are playing currently.
Enter your Spotify username to the field and begin the authorization process.
During authorization Spotify will ask you to give this service permission to read your currently playing information.
If you have done this already at some point Spotify may not ask anything and you are redirected directly back here. This is normal and all is well.
This service does not have logout functionality. Close your browser to clear your session.
