I'm a bit suspicious of this, but if all the information is accurate it's pretty astonishing!  I'm leaning towards what megajosh2 and cool4dude said though, the songs sound like they were recorded recently but produced in a "gritty" fashion to sound old. but I'm not sure what there is to gain by blitzkrieging an elaborate hoax like this on gullible last.fmers. I wonder if the Rhodes' family will sue Katy Perry for plagiarism, considering "I Kissed a Girl" blatantly took a bit from "If You Love Me". Or the other way around? Time will tell.
