does anyone know the difference between the 2 remixes of the song

robert vadney - sadness in disguise (original mix)
robert vadney - sadness in disguise (express mix)

I want to buy the song but both samples off beatport sound the same, I was wondering if maybe express mix is only 3 min or something...I want the best version of the 2 but if the express mix is only 3-4 min, i'll get the original then
