Hi aiyanabanana,
Thanks for your question. It sounds like you are wanting to see all of the songs your marked as a favorite in your Music app. Marking these songs helps Apple know what your preferences are. It does not automatically create a playlist for you. So, if that is your goal, you would need to create a playlist of your favorites and add the songs to your playlist. The resources below will explain this in a little more detail.
Refine the For You suggestions in Apple Music on your iPhone, iPad, iPod touch, Mac, or PC
When you join Apple Music, we ask you to choose genres and artists that you like. We use these choices to give you music suggestions from our experts who know and love music, in the For You section of the Music app. You can help us refine your suggestions even more.
Choose more of your favorites
When you listen to songs and albums that you like, let us know. We'll use this information to give you better suggestions. When you find an album or song that you like, tap or click once on the heart. (If you tap the heart on accident, just tap or click it again to clear it.)
When you hear music that you like on Apple Music Radio, you can add it your library to listen to later. You can add it to My Music or just add it to a playlist.

- Tap the More Options icon
