"Eien no Uta" (永遠の詩, lit. Eternal Poem) is a single by Japanese singer Mika Nakashima. The title track of the single, a reggae-inflected ballad with producer Stephen McGregor, was used as the theme song of the movie Southbound, released in October 2007.[1] The single's other song, a cover of Cole Porter's "You'd Be So Nice To Come Home To," was made with jazz band Katteni-Shiyagare and previously included on the Katteni-Shiyagare tribute album, 'Let's Get Lost.'[2]
