Meaning, do you listen to EVERYTHING you scrobble, or do you sometimes leave music on/scrobbling when you're not there?
I'd say I'm mostly a true listener. Once in a while I leave for 2-3 minutes with the music on, but it's only to get laundry or whatever, and I don't count that!
One thing I do, however, is "compensate" for songs that don't scrobble properly. If something doesn't scrobble because of a server hiccup, or an update glitch, I'll put the song in a "temporary" playlist and deliberately let it play when I'm not there to make up for the time it wasn't collected by the servers. I'll do the same if something's mistakenly tagged improperly--delete it from my library, then correct the tag and play it later when I'm absent to make up for it.
Yes, I realize how obsessive-compulsive that sounds.
So I guess my library is VERY accurate playcount- and tag-wise, but not always accurate time-wise.
