Yep. Straight music, no talk or anything. No commercials either. just straight up, categorized music. I'm rockin trivium right now. You get to pick your song, you don't have to wait. You can also filter by each artist(s). Very good for the office.
All my old metal was on cassette tape. I didn't buy in to the CD era right away. I think I only have Vulgar and Cowboys on CD. I bought them twice because my first ones got stolen. I had every Metallica, Megadeth, Slayer on cassette.
