Which preposition to be used for the below statements? Of, From, or By?

I’m confused with which preposition to be used for the following sentences. A friend of mine told me that is should be "from".

1.Those opening songs are FROM Lady Gaga.
2. Those songs are FROM Beatles."

I believe it should have been of or by because the above sentences are pertaining to songs sung by the said artists. It shows possession.

Many thanks!
