My Question or Issue

I noticed recently that the song playing is switched to the next song without being finished, and the next song is also not started from beggining, but from around second 15. So the behavior is like this:
1. Song A playing

2. The time bar shows song A is in the last second but obviously it is not

3. The song being shown on the device switches to the next song, say song B, the time bar starts from second 15, and still song A is playing.

4. After around 5 seconds, song A is stopped and song B is playing, but not from the beggining of the song.

and this continues.

I will be grateful if anyone could help me.
