If I mark a song as "favorite" by the star before it, it marks all songs of this artist.

Is there a way to mark only a single song?

I would like to mark a song I've heard in the radio by mobile phone for example and download it later.

 

I hope someone can help me.

There is a "save for later" button. It does exactly what you want.

Sounds great. But I can't find that button. Is it on the list of all artists and songs?
