In a lot of ways, a great musical collaboration is a lot like a great, loving relationship. First off, you need chemistry, but you'll also need trust in your partner and some understanding as well.

Take Eminem and Rihanna, for instance. Their musical chemistry is undeniable, and all of their collaborations are edgy and catchy too. Drake and Nicki Minaj have a similar magic between them in the studio, and now that Valentine's Day is here, we decided to go ahead and play musical match-maker.

These 10 musical couples have already captivated our ears, but what if they took things to the next level and became couples IRL?

We're not trying to start any trouble-- OK maybe we are.

Eminem and Rihanna

Em and Rih make beautiful music together. These two have already given us huge hits like "Love the Way You Lie" and "The Monster," but these two together as a couple would make more headlines than any song could.

Rick Ross and K. Michelle

These two make real sense after watching their chemistry in Rozay's 2014 video for "If They Knew."

Fat Joe and J. Lo

These two have been friends and collaborators for a long time, they're both boricua and from Bronx, New York. It's a match made in hip-hop heaven.

Wale and Tiara Thomas

Wale and Tiara Thomas have had an up and down musical relationship, though they recently patched things up and performed at an NYC concert together last month. Maybe they aren't fit to be a couple, but we just wish they'd make more songs like "Bad."

Drake and Nicki Minaj

Drizzy has had his eye on Nicki for the longest. This needs to happen.

Jhene Aiko and Childish Gambino

Are we sure these two aren't dating already? Maybe not, but they look perfect together.

Mary J. Blige and Method Man

We went old school with this pick, but ever since their 1995 classic "I'll Be There for You/You're All I Need to Get By," we've always hoped these two would become something real.

Tinashe and Kid Ink

These guys make beautiful music together. We're guessing Kid Ink's "Body Language" is just the tip of the iceberg. If they actually coupled up, imagine the hits they'd make.

Nelly and Kelly Rowland

After 2002's "Dilemma," we've been waiting for these two to become an item.

Ashanti and Ja Rule

Now we know Ja is married and Ashanti has had a few high-profile relationships of her own, but in our rap fantasy world, they'd be together forever.
