The LiveJournal™ Music Chart now has an RSS feed () tracking any new songs hitting the top ten. Since I don’t check anything that doesn’t have an RSS feed, this is a great way to make sure that I’m alerted to any music becoming popular without my permission. Each entry has a Magnet URI, which should trigger automatic P2P searches. (For example, this link should search for the Gnutella specs.) This doesn’t work in LimeWire or Gtk-Gnutella at the moment, so there are links to Google and Amazon searches as well, and iTunes (untested, following the format given in this blog entry by Erik Barzeski).
