Go take a look at how many songs are called “Hold On.”

There are certain aspects of a musical composition that, by themselves, cannot be claimed as unique intellectual property. The title is one of those. And there are a very finite number of keys and modes you can use. So with the combination of the two, you’re safe.

Now when you begin to combine things like lyrics, melody, hooks, chord progressions, etc, it becomes a gray area. Conscientious songwriters will take care to ensure their new material doesn’t accidentally mimic someone else’s work. And if someone wants to take you to court, they have to prove intent on your part to copy their property.
