Thinking about the player "timed out"

When I went to bed last night, my brain hole thought ...

At present, most of the player applications on the phone have timed out of this function, think of the main requirements of this feature should be: (1) The user wants to be able to automatically close the application after fast asleep.

And then after this, there are some extended needs: (2) such as through this function to time, for example, today want to run 30 minutes on a regular 30 minutes.

Although it is possible that similar requirements (2) These will be the main needs of some applications ... But the main point here is to first talk about demand (1).

The current general (not sure) feature is "timed to pause the current playing music" so there are a couple of questions for users who want to listen to the song until they fall asleep:

1, the user is not sure about how long it will take to fall asleep, so hope that the countdown time is not accurate. For me, most of the time I still have to wait until I'm still awake.

2. Some genres may be too intense to scare people. However, this is not much of a matter of timing.

3, perhaps to be supplemented?

As far as I am concerned, the problem of 1 may be more serious (although it is actually very small, it is not serious at all ...). ）。 Sometimes a sudden pause in music can affect the state of being asleep. Sometimes the song of the sudden interruption of the melody will be echoed in the mind, perhaps soon after the fall asleep, and perhaps will rise again time a 10 minutes ...

So I was thinking, "time off" this function to change a little more to reflect the "human care": When the end of a song, to determine how long the distance to the end of the time, if the remaining four or five minutes, play a song of the length of the same, and so on when the first release is finished as a time. (later to think about so many actually just change the time to "30+-5 minutes" This type is OK)

This may improve the "going to sleep but still want to finish this song" question. Although I did not try to sleep at the time, but if I am listening to the song to do something, when the status of a song should continue to play the song will not play down, I generally do not notice; but if the song is interrupted, I will have a sudden feeling to see what happened. Maybe it's the same in bed, I think.

But there's a little bit of a problem with this approach:

#1, the first is to deceive the user. This should be good to do, directly after the chronograph interface with "-minute or so" the word is good.

#2, if the user just time 5 minutes, then not 1 to 2 songs will end? It's a matter of opinion, if it's me, I'll let it take effect after 15 minutes (that is, the word "left and right" after 15 minutes of the input timer).

#3, if the user in the library is 10 minutes or a few hours, such as how to break the symphony? This should be a mandatory judgment: if at the end of the time, the currently playing song length is too long (for example, the remaining 5 minutes or more) is changed to the same as in the past to pause the song, if the remaining length within the allowed range to play this song.

4, how to choose a song of the same length of time?

(When I wrote here, I suddenly thought that as long as the time to change to "30+-5 minutes" This type can be, the average length of the song is within 2-6 minutes, if the rest of the music after the end of the 10 in the range can be ended, and then with the above several solutions should be able to solve the problem very well)
