  QoE is traditionally evaluated by using short stimuli usually representing
parts or single usage episodes. This opens the question on how the overall
service perception involving multiple} usage episodes can be evaluated---a
question of high practical relevance to service operators. Despite initial
research on this challenging aspect of multi-episodic perceived quality, the
question of the underlying quality formation processes and its factors are
still to be discovered. We present a multi-episodic experiment of an Audio on
Demand service over a usage period of 6~days with 93 participants. Our work
directly extends prior work investigating the impact of time between usage
episodes. The results show similar effects---also the recency effect is not
statistically significant. In addition, we extend prediction of multi-episodic
judgments by accounting for the observed saturation.
