Sade opened up to Jay-Z's blog site Life + Times during a recent interview, where she spoke about her regrets not putting Jay-Z on her 2010 song "Soldier Of Love."  She told Life + Times that despite having put Jay-Z on the remix to her single "The Moon and The Sky," if given the chance she would go back and have him record on the "Soldier Of Love" track with her as well.

"I would have asked Jay-Z to rap on 'Soldier Of Love' in 2010. There's not much else I would change – the mistakes I've made have made me grow braver."
