They apply to a mass-market and all demographics within society. For example, Lady Gaga has a niche in the market (teenage gay guys and teenage bullying victims) that she focuses on.

Adele appeals to teenagers and adults of all ages, while Frozen appeals to kids, teenagers and their parents/young families as a whole, as well as adults of all ages who remember the last golden age of Disney musicals in the early 90s (Little Mermaid, Beauty and the Beast, Aladdin, Lion King)
