An anonymous reader writes "I tried out Google Music, and I liked it. Google made me swear that I won't upload any 'illegal' tracks, and apparently people fear Apple's iCloud turning into a honeypot for the RIAA. My music collection comprises about 90% 'legal' tracks now — legal meaning tracks that I paid for — but I still have some old MP3s kicking around from the original Napster. Moreover, I have a lot of MP3s that I downloaded because I was too lazy to rip the CD version that I own. I wanted to find a tool to scan my music to identify files that may be flagged as having been pirated by these cloud services; I thought such a tool would be free and easy to find. After all, my intent is to search my own computer for pirated music and to delete it — something that the RIAA wants the government to force you to do. But endless re-phrasing on Google leads to nothing but instructions for how to obtain pirated music. Does such a tool exist or does the RIAA seriously expect me to sift through 60 GB of music, remember which are pirated, and delete them by hand?"
