A user's access to content may be managed by determining a mood originating point for a present track for a user, with the mood originating point being related to a mood indicator for the present track, identifying a mood destination for a user playlist, the mood destination being related to a mood indicator for an end track that is targeted for the user, and calculating a mood transition from the mood originating point to the mood destination. The mood transition includes one or more intermediary tracks between the mood destination and the mood originating point, such that a quantified mood transition between two tracks in a user playlist including the present track, the intermediary tracks, and the end track, is less than an identified mood transition threshold.
