The Grammys are this Sunday, and while it didn't make it into the running due to it's October release, Calvin Harris' platinum-certified 18 Months could have easily been in the Dance Album of the Year category (maybe next year?); while he was working on the album, Calvin spoke on making it more of like a "compilation," where he's collaborating with a number of different artists. You had to have heard the huge singles with Rihanna, Ne-Yo, and Example, and we thought it'd be fun to dig into the album see which one of these collaborations worked out the best.

During our thorough scouring, we found it interesting to see the different ways an artist works when he has a certain individual along for the ride. Sometimes, they take their sound into a different route, while others feel more like a cash grab. Calvin's album runs the gamut, and you might be surprised as which collaborations we consider heads above the rest.
