The older a torrent is the better chance many of the seeds have fallen off over the years. Since joining a year ago and downloading over 300 gigs worth of material there's only been two or three things I have been unable to download after leaving it in my queue for 24 hours. The newer uploads definitely get users downloading so it wont be for nothing. As far as your 'pretty unknown' Swedish death metal bands I think I have multiple copies of both Grief albums as well as the Sins, and Disinterment isn't too hard to find here in the states since it was released on Sevared Records. I've yet to find anyone who has as much Swedish death as I do from my 25 years of CD collecting (13,000+ original CDs). My problem is I can't find anyone to help me understand how to make torrents/seeds from my originals.
