I just pondering.
I was a 90s kid, and remember the charts were full of various bands that made music that appealed to kids. S Club 7, Steps, Bewitched, even the Spice Girls to an extent, to name a few. As a child I loved this music, but it's quite surprising now, as an adult, to remember how popular these songs were, as adults would have been buying it. The bands, their music videos, their image, was usually aimed at kids too, not adults. I feel I have grown out of this music now and can't understand why adults would like it, except for nostalgia reasons.
These days the number 1s are more often than not more 'adult' songs, and music aimed at kids doesn't really chart well. What has changed?
