Creating a 'niche'

It is important for solo artists to create a 'niche' as this is what

separates them from other artists, and gives them a unique selling point.

If artists don't have a niche, then they will just be like everyone else and won't stand out from the crowd.
For example; eminem's niche is his ability to mock other hip-hop artists in his songs.

Lady Gaga's niche in a way is her identity in general, the clothes she wears are always very unique and original. She has got her very own brand identity, separating her from other similar artists.
