Singing a cover of any song could be a great challenge for any musical artist, whether they be famous or not. Switching up the tempo of the song, as well as a few changed lyrics and beats can help an artist transform a song into an entirely new piece. Doing this with famous celebrities and songs that have reached the top of the billboard, however, is a very, very different story. Check out these top picks of celeb music artists covering chart-topping hits!

One Direction singing Rihanna/Kanye West/Paul McCartney's "FourFiveSeconds"

Introducing their signature boy band sound onto this song was a very cool thing to hear, on a very popular song originally featuring Rihanna and Kanye.

Birdy singing Kygo's "Firestone"

This quaint but strong voice really conquers this cover of this electronic dance song.

Taylor Swift singing Vance Joy's "Riptide"

In this cover, Taylor brings her magical voice to the track, keeping much of the song very similar to Vance's original.

Bastille singing Miley Cyrus' "We Can't Stop"

With their indie pop vibe on a pop hit, this version does seem a little odd but is still cool to listen to a song we all know the lyrics too, sung in a different genre!

Ed Sheeran singing Christina Aguilera's "Dirrty"

Known by many as the king of covers, is there any song that Ed Sheeran can't make a stunning cover of? A kind-of acoustic version + a little rap break = check it out!

Miley Cyrus singing Lana Del Rey's "Summertime Sadness"

Miley Cyrus has putting out great covers of many songs for years now, with her top performance most likely being Jolene. Her version of Summertime Sadness is no different, with her amazing vocals and soothing sound.

Usher singing Foster the People's "Pumped Up Kicks"

This song is such a crazy switch up fro Usher's usual R&B genre, as he adapts the more rock genre of the original song.

The 1975 singing One Direction's "What Makes You Beautiful"

This song is nothing different than The 1975's alternative rock genre: they transform this song into basically a whole new song that happens to have the same lyrics.

Little Mix singing Whitney Houston's "Dance With Somebody" and Natalie La Rose's "Somebody"

Harmonizing non-stop on this song mash-up, these girls show off their serious talent while giving us an incredible combination of these two songs.

Sam Smith singing Tracy Chapman's "Fast Car"

I have to be honest, I am a little biased with Sam Smith's angelic voice, believing anything he sings is absolutely heavenly. Nevertheless, he slowsthis song down even more in his interpretation, seemingly to make this song even more of a lyrical masterpiece.

Disclosure with Sam Smith singing Drake's "Hotline Bling"

This cover is definitely one for the record books. With Disclosure's electronic beats behind Sam Smith's interpretation of this hip-hop single, you may wonder if this version is actually better than the original...(Sorry Drake!)

Demi Lovato singing Hozier's "Take Me To Church"

You have to listen to this rendition. Here, do it now. Her vocals and little switch up on this song shows of her unbelievable musical talent. Hozier should be more than proud over this cover.

Lorde singing Jeremih's "Don't Tell 'Em"

Lorde's interpretation of this popular rap song is absolutely shocking. Just imagine, Lorde slows down this popular club banger and makes it almost eerie and mysterious. Listen to this cover!!

Let's be real: if a talented artist covers another one's very popular song, who wouldn't want to listen?
