mu’sic (mŭ’zĭk), n., any art over which the Muses presided, esp. music, lyric poetry set and sung to music, fr. mousikos belonging to the Muses or fine arts.
Webster’s New International Dictionary, 2nd Edition, 1954.
For many writers music is the muse itself, inspiring their writing often to the point of being inseparable from it. While the desire to use the lyrics of others in their work is strong, writers find that actually doing it is a challenge.
I discuss those challenges in a post on The Better Novel Project:
In order to use someone else’s lyrics in your fiction without infringing that creator’s rights, you need to either:
1. Establish that the song is in the public domain;
2. Obtain permission from the publisher of the lyrics;
3. Satisfy the requirements of the fair use defense; or
4. Avoid the use of lyrics altogether by just referring to the song title.
