Relapse is the last album by Eminem mainly produced by Dr.Dre. It was Eminems come back, and could be described as the debut of the "new" and sober Eminem.
GKMC is Kendrick Lamars debut album. It is also mainly produced by Dr.Dre. It is a new style for Kendrick and is very popular and was very successfull.
Both albums did well. But the question is, which do you think is better?
If you can not compare other artists albums and this is a very stupid thread please delete it. I thought it would be cool to compare since they're both some what debut albums.
