The archives, thankfully, are still (largely) available. But how, pray, would you download hundreds of songs scattered over 26 pages? (one per each letter in the alphabet)
If you use Firefox (and if not, you should. Not because it’s the best browser, but becaue of the add-ons), then it’s simple — look up FlashGot or DownThemAll!. The former is more configurable, I believe (you get to use your own download manager), but the latter is probably simpler to use.
Caveat lector: the (rough guess) 70% or so of the songs that still have functional links total up to more than 2GB’s worth. Will probably post a Torrent link on Mininova once I tidy them up a bit.
