Sammy's poem is about being trapped in a loop of self-doubt. The speaker compares their thoughts to a record going round and round, but the comparison has a twist: a record is supposed to play music, and here there is none. All that's left is noise, a voice of words insisting "I'm never going to make it."
The feeling is exhausted and a little helpless. The speaker gets dizzy from the spinning and, in the end, gives in to the negative thoughts "once again." That last phrase suggests this has happened before and probably will again, which makes the moment sadder.
The shape of the poem helps. The lines slide further to the right as it goes on, so it seems to drift or sink, like the speaker losing their footing. The short lines and the break before "Music" make the silence feel real. The mood is heavy and quietly discouraged, but it's also honest, since the speaker names the problem plainly.
