After destroying KaZaA, the RIAA has
marked AudioGalaxy for death. The AudioGalaxy file sharing service attempts to filter copyrighted songs, but that won't save them, as the RIAA's modus operandi is to throw lawsuits at the target, Scientology-style, until they run out of money and die (or are bought out by a RIAA member and emasculated).
In short, AudioGalaxy is, for all intents and purposes, on death row.
If you've got some out-of-print rarities you want, you'd better snarf them now.
