Can't find apple music saved songs

Hi,

I'm new to Apple music and am beyond confused at this point.

I connected my iPhone X to my car and it booted up carplay. I then said,"Hey siri. Play something I like." Apple music (I'm assuming) loaded up and started playing music. A fair amount of it I didn't have or hadn't heard before. As I came across songs I liked I started pressing the "+" button and then the "..." Button so I could click the heart button.

My question is, what now? Where do I find these songs so I can listen to them again. I can't remember the names of the songs, hence the reason I was clicking the + button. I can't figure out any way to view these songs on my iPhone or iPad and I can't find any answers by searching (at least none relating to ios 11, which must be different than previous versions.)

Any help would be great. I'm on a long cross country road trip and this is a great opportunity to discover some new music, providing I can actually save it to review later on.

Thanks.
