song of the song stuck in my head

today I went out walking in the rain, in the rain
I felt my own voice talking in my brain, in my brain
talking of the things I can't explain, can't explain
such as all the words that dogged me through the rain, through the rain

tonight I'll go out walking in the park, in the park
I'll wear thick shoes and walk fast in the dark, in the dark
alone with all my voices i'll embark, i'll embark
on a journey to the party store for chips and Cutty Sark

tomorrow I'll go walking in the rain, in the rain
with mashed-together lyrics in my brain, in my brain
my steps will squish the rhythm and refrain, and refrain
of songs with choruses that end in rain, end in rain

nothing lasts forever, even rain, even rain
rivulets go running for the drain, for the drain
nothing lasts forever in my brain, in my brain
of each synapse only silence will remain, will remain
