Hmmm... [this will be largely off-topic]
I used to think that all my music was at least good. Especially since I do not store whole albums or even can cut a track to pieces, leaving out what I did not like
But for months [years...] now I have been evaluating and re-evaluating my music. Or should I say: taking a note of change of my taste
And still [with that new taste of mine] there are those rare tracks that I just love to hear to and that supposedly good rest [that I just know I will get rid off at some point] and that new-at-least-good rest [that I just evaluated]. So I should write now: only time will tell, if I should start using that stars and some percentage based play system like yours [as I use Winamp] or continue with the purge
But as my knowledge and experience increases, I bet it will be the later one of those two options. And that is because also of this simple question: how much music one person needs [at least for personal use / leisure time related activities]? If running simple math tells me, I will be able to hear any file [by average] only once a year, then pulling it back by tempering with the chance of it being played [based on the star system] would mean one playback per 2 or 3 years for those not-so-super-extra ones? And so I have too much of it- thus need to continue the purge [of those not-so-super-extra ones]
