Not sure about it, but Q posts soundtracks without WORDS/lyrics.
Personaly I don't like music with lyrics and there is reason for that. From my observation, people tend to identify themselfs with music and this is where, I think, mind control happens. Those "popular" songs are written in the way, which makes people think, that that song is about them and their expierences, why is that?
And how often you hear people say: "This is the song which brings me memories from last summer" or something like that.
I think, there is the reason why lyrics/songs "Echo" in our heads
