A FIXME would be helpful here.

How about m_currentSession?  I think "current session" makes more sense than "most recently active session"

Nit: this could be an early return.

Ditto.

Ditto.

Shouldn't this be above the "if (!restrictions & ConcurrentPlaybackNotPermitted)" above?

if (!m_currentSession || !m_currentSession->canReceiveRemoteControlCommands())

This is unnecessary, we already called setCurrentSession() above.

Move up?

canReceiveRemoteControlCommands()?
