Recommendations for Thievery Corporation

[Sappys Curry]

I bought Radio Retaliation and I like it. What TC album should I buy next. I have four to choose from (their 1997 release, Mirror Conspiracy, Richest Man in Babylon, and the Cosmic Game). Of those four, which should I go for next, and which should I go for after that? I'm still getting into the group. I went to delve further into their music.
