I tried to recreate a mix tape Kurt Cobain wrote the tracklist for in his published Journals. Songs I could not find were: The Necros -"Blizzard of Glass" and Lush - "How does it feel to want".
I couldn't verify the existence of PIL's (Public Image Ltd. I assume) "Whatever" but he may have meant "Memories" which features the word "whatever" prominently. Lush's "How does it feel to want" also seemingly doesn't exist.
