Also you are more attached to the music you were brought up with.
Lol for example, I was really into music in the late 90's and boy bands and Brittany Spears.
Now the music is nothing good, (very catchy though), I look back at the songs nostalgically and think they are better then they really may be.
lol this song is hilarious, I listened to it and I liked it, I can see why it was such a popular song and popular even today.
