The song of the day is Echo by Bad Meets Evil (That is Eminem and Royce da 5'9) featuring Liz Rodriguez of the Hell The Sequel Album released in 2011. Twenty eleven  was a very good year, I remember a lot of good rap and even other albums came out that year. But back to the matter (open and close...) The song began with the chorus from Liz the song talks about chasing the "Echo" no matter the situation, then Eminem and Royce had their own separate verses and just did their thing. Actually in this song I think Royce had a better verse than Eminen, I really like the way he started the verse and his word play was too on point and he was just too consistent through it all. Liz Rodriguez was also spot on on the hook and her vocals were also in the back ground through all the verses. This isn't one of the most popular songs on the album but still its one of my favorites.
