Gucci Mane feat. Young Jeezy - So Icy (Alternate Version) (2005)
I had not heard this version of "Trap House (2005)"'s "So Icy". I've seen it labeled as both a remix and unreleased version, so I'll just call it alternate.
There is no Boo feature on this version, Young Jeezy has a different verse, and Gucci Mane has three verses. The chorus and outro are the same as the retail version.
It was a good call for Gucci/Big Cat to use the version that ultimately made "Trap House". This one is a bit too long, but Jeezy's verse is ear-catching as he was on fire at this time. Check it out below:
