"Dragostea Din Tei" sung by the Romanian pop band "O-Zone" has some great music and lyrics. I hope people have time to check it out, they can watch the video on YouTube. The original video from the Album can be seen HERE. The original lyrics of the song can be seen on THIS website. Also there is an English version, the lyrics for that can be found HERE.
But this song became more popular because of a guy lip-synching the song energetically over his webcam and posting it on the Internet on the site "Newgrounds" in 2004. It had a record views of 13 million. That video became more popular and was known as the "Numa Numa Dance" video. It was performed by some 19 year old amateur Gary Brolsma. For viewing that video click HERE. This video is now been posted over many sites including YouTube. The amazing thing about this video is that it created something known as the Numa Numa Phenomenon. It is also sometime considered as an Internet Parody.
Based on this many more videos have come up with the same song posted by different internet users with Webcams including a competition for $45,000 for the best Numa Numa Dance video.
