This needed a serious google as I have never heard any of these:

Rachel's Song by Vangelis Picture postcards from L.A.by Joshua Kadison Little Rachel by Eric Clapton Rachel by Marley's Ghost Rachel by Lil' Chris Take Him Back Rachel by Basia Rachel by Al Martino The Lady Rachel Kevin Ayers Pagan Rachel byThe Flamin´ Groovies Rachel by Soul Coughing Rachel's Flat by Badly Drawn Boy Rachel's Song by Stone Sour

I suppose Rachel doesn't rhyme with much
