Indeed. I think everyone eventually reaches an age where it seems all the new music sucks.Go forward another 10 years and ask kids about the music of the noughties and you'd get a similar reaction. Our music taste can be largely influenced about the era in which we grew up in.
With things like Pandora and other music apps, these days I think it's easier for older people to find new music they like. Maybe they'll still think the Top 40 sucks, but there are convenient ways to get exposed to new music that may never end up on the radio.
