Bubba Sparxxx should not have been in the list - I guess they meant critically unappreciated in his case, but for me personally he actually had way more commercial success than he should have ever had and that alone should have disqualified him from the list
P.S. I did not criticized The Jacka as an MC - he's a quite good MC. Unfortunately, a lot of very good MCs never make even a single decent solo album, which is obiosuly a lot more tragic than when some wack MC makes a crappy album, and is even more so when it's the Mob Figaz who as a whole have such a solid catalogue (despite putting quantity over quality at times) we're talking about
