I've seen that a lot of people have already suggested this so I'm sorry for being repetitive but I really think that we should be able to see Friend Activity on Mobile. Music brings people together and I've had plenty of great conversations by people seeing my recent activity or me seeing others recent activity. It's also a great way to find new music. It's just so good it shouldn't just be limited to Desktop.
