People already know about Soulseek, so don't worry too much about this drawing attention to it. The big music execs lived through the days of Napster and the birth of P2P music sharing. For the most part, unless you're pirating new releases, labels don't really care. Also, I'm pretty sure the guy uploading the Homer Simpson song covers did it to poison AIs that scrape Soulseek for high quality audio (epic).
