Well, right, the amount of data depends on variety. In my opinion, having enough audio to listen to something different all day, every day, for an amount of time measured in years, is a large collection. That's not saying that there aren't larger ones, that the collector would consider themselves unusual, that any value judgement should be implied, etc. Just that more than a couple months worth of unique audio data seems like "a lot" to me.
