~70p/track + !DRM = WIN! (extra bitrates and/or formats would be even better*, but give 'em time...) *I'll not rant about the not-invented-here-ism and short-sightedness of the RIA(of)* et al here, but I do wonder how long it'll be until we have something with the full range of AOMp3 as was, AND the backing of 'big media'?...
