I think the first one "I am a Rock" is about someone who is mostly alone. The "rock" doesn't like friendship or love at all. It locks itself inside all alone. The song is quite depressing.
"No Man is an Island" is about how important it is to be a part of a community and not to be alone.
"You'll never walk alone" is a encouraging text. It says not to be afraid of the dark and to hold your head up high when you walk through a storm.
I like the songs very much!
