Query: let down.

What an amazing song, and it is my favorite on the album.I was really looking forward to the cd single being released, and waited around 2 months for it to finally come out.When it did come out in Australia, it only contained the radio edit, junior sanchez mix and new song history.Looks as though we only got Jump part 2 here in Australia.I was very disappointed that the other remixes were not included, and I did not like the junoir sanchez mix at all.I was really looking forward to hearing the Jaques Lu cont mix, as I have enjoyed his past work for Madonna, and also the extended album version.Unfortunately neither were included on the cd single in Australia.
