unlikely hit song?

over half a billion hits!

Odd singing voice, but then so is Willy Nelson, and he's been a hit for years.

A few months ago I was kicking around on youtube, seeing what was the most viewed in the music world. Sadly I didn't like many of them, but this one stuck with me as enjoyable to listen to.

87 million hits
Another I liked was this "nordic" song. Based that description on the participants in the video. Looked up later and discovered it was French but based on Sweden admiration? The video reminded me somewhat of ABBA.

Ran across this one first on a Linux video for Solydk and had to search it out. Children singing, fun video too of child play. Really neat toilet paper guns they use!

only 5 million hits, but reminded me of ColdPlay, also the color Green used like Cold Play song on "Yellow".

This is by a group from Sweden. They do have a connection to ABBA, consulting with the men from that group on songs. Seems to be a lot of controversy over the video and Ralph Lauren product association in it. Some other objections exist. The singer is a black man Aloe Blacc, seen near the end of the video. He's married to Maya Jupiter, another singer of Mexican-Turkish background. In 2013, Blacc co-wrote the song "Wake Me Up" with Swedish DJ Avicii.
With Blacc on vocals, the song reached #1 in 103 countries and became
the fastest selling single in the UK, selling 267,000 copies in its
first week
