To find the total number of seconds the playlist will play, we need to multiply the number of songs by the average time of each song.

Total number of seconds = 1,900 songs * 3.5 minutes/song * 60 seconds/minute

= 133,000 seconds.

We can express this answer in scientific notation as 1.33 × 10^5 seconds.

Therefore, the correct answer is "1.33×10^5 seconds".
