In this day and age, everything is about what’s trending. From clothes and fashion to bands and rappers, it’s important to know what’s hot. Going viral will make or break an artist, so knowing what’s on the rise will be the key to predicting which artists will dominate the charts. This month, we look at who has the right ingredients to start off the year with a bang.

Let’s kick start the viral countdown with Mark Ronson’s “Uptown Funk,” featuring Bruno Mars. It was a sensational effort by the two stars. Ronson, who has been apart of Grammy-award-winning albums for artists like Amy Winehouse and Adele, infused his funky style with the super popular Bruno Mars and made an instant, viral hit for the masses.

The song was officially released about a month ago and has already generated over 40 million views on Youtube, but the most interesting part is that they were able to popularize a style of music that a lot of people thought was dead, Funk. The song is super groovy and Bruno Mars pulls in some soul with his Prince-esque outing, so it was crafted for success.

Next up, Sia’s “Chandelier.” We are talking about over 385 million views on YouTube and probably the most covered song on Youtube by up and coming singers. It’s also on every radio stations around the country, so it’s very unlikely you don’t know what song I’m talking about. I have to give it to her, this was an instant classic and viral doesn’t explain how contagious this song has been to music listeners around the country.

It’s energetic, emotional and a true showcase of pure vocal talent.

Though 45 million views doesn’t seem like a lot compared to 385 million, Hozier’s “Take Me to Church,” has been quickly gaining popularity over the last two months. The video quickly gained buzz because the overtone of the song implicated that being gay was big joke to some people. In his own way, he stood up for gay rights and he happen to do it in a musically convincing way. He might not be on the top of the YouTube list, but he holds the top spot of Spotify’s Top 50 and Viral 50 with a weekly average of about 13 million streams.

This song is extremely soulful and just enough to make it great.

Here’s one that no one expected. Lo Fang covered “You’re The One That I Want,” and it pulled in about 1 million streams on Spotify and about 2 million views on YouTube in just the last month. That’s about three times as much as he has gotten on his own original work, so that tells you how much people were needing a modern day rendition of the Grease classic.

Sam Smith also makes our list with his rendition of “Have Yourself A Merry Little Christmas,” but it’s Christmas season and it’s Sam Smith, enough said. The 2 million views on YouTube in its first week doesn’t surprise me and landing in the Viral 50 on Spotify is no shocker either.

That was our monthly viral round up of the top five most infectious sounds on the web.
