Yes, the chorus sounds like Strike Of The Beast, and nothing wrong with that. Strike Of The Beast is a great song. Total Death is a great song. Metallica has Trapped Under Ice, which Kirk took the riff from the Exodus song Impaler. All great songs. Its all good, just rock out!
v Whatever gave you that idea? 1984 was not the stone age and we had already a postal system, you know. Tape trading started as part of the mail art movement in the 1970s. Rough Trade played a key role as one of the first distributors and then came the fanzines. A whole generation of fanzines was built upon tape trading and in the early 80s every metalhead with an interest in underground music was into it. Believe me, i was there ;-) I remember watching the "Get thrashed" documentary the other day and they mentioned the importance of tape trading via fanzines back then by saying, "Tape trading was kinda like an early version of the internet". And that's true. Fanzines and independent distributors operated worldwide since the late 1970s.
