Same feelings here, also since Gigi has post both track in casadag on the subforum "Musica: CD / Vinilli / Digitale Store: Gigi d'agostino"
Think we are facing a New release, and following the style, giving in these track I'll guess a Smoderanza volume 2
Gigi has explained on casadag that there are 2 Versions of Hung up.
1 he used to play in radio and during live sets
And the other one, the one uploaded today, was for travelling and personal purpose, that's why some mixes have "personal Mix" in the subtitel.
