Yeah, I’ve always had the same thought.

Another musical pet peeve of mine is when, usually during the intro, a song doubles the number of bars for a sequence, basically repeating itself for no good reason.

My ear is ready for the song to kick in, but at that moment it just repeats the previous 8 bars. Every time I think “really, we need to do this 8 more times? Can’t we just get on with it?”

It’s like the musical equivalent of waiting in line.

Not sure about pop music, but in the EDM world, I've always considered this as an artist actively considering how the DJ will use this track. For DJs that simply fade in/out of one track to the the next, they wouldn't care. However, for the DJs that actually beat match and mix tracks together, this added phrase at the head of the track allows for a much more seamless mix before the song "kicks in".

Sometimes extended intro repetition puts you in trance. Enter Sandman for example.
