If I wanted to use a name of a band in my lyrics for a song, example:

When the Motley Crue become classic rock ? (Bowling For Soup - 1985)

Would I need to pay the artist to use the name ?

Depends on whether the original artist wanted to take it further, it wouldn't cost you anything to start with. But a local band to me Lassie Come Home were threatened with legal action by disney for the use of Lassie.

Also please read the FAQs for each forum before you post this forum is for Original lyrics writing only.
Filth, pure filth... That's what you are.
