I think the there is alot of difference when it comes to the style of music. First, old songs focuses on the lyrics and what does it really want to tell about. While the songs of this millenium focuses on the beat with a minimal lyrics. I am a millenial but i'd think that 90' s songs are bettet because if you'll listen to them it is like it is telling you story. Most of the songs in the 90's can make you relate. On the other hand, most of the new songs are for party goers with a lot of beat, although the lyrics are also good but they emphasize the rhythm and beat.
