Let us add only a part of a song into our playlists

[benedicteeee]

There are specific parts of certain songs I really like, meanwhile I maybe dont enjoy the other parts as much. Therefore it would be really great if you could add only a certain timestamp to songs you add to your playlist, so you dont need the entire of every song. For people downloading this could also save some space potentionally.

Would your idea allow for ending at a certain point, too, rather than just having a starting point that will play to the end of the song?
