far away was released on May 17 2000 and this CD was sent to that person on April 27 2000 (Heisei Year 12). Also its written "O.A. yoroshiku onegaishimasu", O.A. means On Air so it was probably given to a radio or TV channel to play it "on air". Also there's written "this time there is only one song (in the CD)". It's definitely for promotion purposes
