Ability to listen to song choruses only - Deezer song preview

I think this is for us that want a quick beat, straight to the “good part” of a song which is usually the chorus/refrain or we don’t have much time right now & want to hustle. For instance, when I am listening to the US Top 100, I tend to

1. open up the player,
2. browse the song until I find the chorus part,
3. listen to it a bit,
4. if I like it I heart it to hear it another time, else I move on.

Now, in Deezer free you provide a 30sec preview of the song that is, most of the times, the chorus part or the good part. What if you provided a function (it could be something like a toggle in the player interface) that once activated it would only playback the chorus part (maybe it is the aforementioned 30 seconds part or if you have a better system to detect the chorus do that!) along with a couple of seconds of crossfade in-between the song parts that guarantee a smooth transition between songs and don’t get cut abruptly or making it awkward or blasts my ears. I think it would definitely be beneficial for dance playlists too. Something like DJ’s do. (please )
