Andreas don't like Gangnam Style =(

[Dylan]

A song can't be good if you dont know the text, you can say the melody is good.

Yes it can. You don't have to understand the lyrics to appreciate them. You can say the song is good, the melody is good, but that you don't understand the lyrics. Also kind of hypocritical to say, as I am sure you listen to at least 1 modern pop-musician, and let's face it, there are way better lyricists out there. Lyrics do not make a song. The singing makes the song. But that is irrelevant as well. You don't need lyrics or even comprehensible lyrics to sing. The very first definition of "sing" is:
sing (sng)
v. sang (sng) or sung (sng), sung, sing·ing, sings
v.intr.
1. Music
a. To utter a series of words or sounds in musical tones.

Still, my point stands. It was a gross overstatement.
