I said "Ah, ok" and walked through the door to the stairwell. He ran through after me and said "Hey, if you want to get some music for free, go to " and I thought he said PierValium.
I thought this might be either a store or a web site, so I said "What?"
After a full minute of back and forth I determined it was a web site and what he'd actually said, after a little game of charades for each word, was "purevolume.com"
I may check the site out later.
