Count the legs, because the music stops when the doors open
The playlist only plays while people are riding. On a typical Chicago night the group boards, rides 20 minutes to dinner, gets off for 90 minutes, rides 15 minutes to the next stop, and so on. A four-hour reservation with three stops might contain only an hour and a half of listening. That is the number to enter.
Leg lengths depend on geography. Hops inside the central area, such as the West Loop to River North or River North to Old Town, are short enough for four to six songs. Crossing the city takes longer: Wicker Park to Wrigleyville or downtown to Bridgeport on a Saturday evening can run 25 to 40 minutes, and a pickup in Naperville or Schaumburg adds close to an hour each way on the expressways. The trip duration estimator and route time estimator give you leg times if you have not mapped them yet.
Some occasions keep the group on board for most of the reservation. A holiday light tour or a cruise along the lakefront is nearly all riding, so the slider should sit close to the full booked time. A club-hopping route is the opposite: many short legs with long gaps. In both cases the math is the same, and only the honest on-board figure changes.

What the skip buffer is really for
The base count is the on-board minutes divided by the average song length, rounded up. The buffer multiplies that count, so the 25% default turns 40 songs into 50. The extra songs exist because a group never listens to a playlist straight through. Someone skips a track after the first chorus, a slow song lands at the wrong moment, or two people added the same hit and the second copy gets passed over. Each skip uses up a song without using up its minutes.
How much buffer you need depends on who built the list. A single organizer who knows the group well can run at 10 to 15 percent. A list assembled by eight friends with different tastes should sit at 30 percent or more, because more of it will miss. Groups spanning a wide age range, such as a family anniversary ride, skip more than a group of college friends who share the same era of music.
The running time shown in the results is the queued count multiplied by the song length, so it will exceed your time on board. That is expected. It is the cushion, and it also covers the unplanned extra 20 minutes when traffic backs up near a stadium or the group votes for one more stop. If your buffer is zero, the playlist ends exactly when the math says the ride does, and rides in Chicago traffic seldom cooperate.
Splitting the list among contributors without chaos
Enter the number of people adding songs and the tool divides the queued total evenly, rounding up. That quota is the most useful number on the page for a group organizer. "Everyone add songs" to a shared playlist produces 200 tracks from two enthusiastic people and none from the rest. "Everyone add nine songs by Thursday" produces a list the whole group recognizes.
A few habits make a shared list work. Set a deadline a few days before the trip so one person has time to remove duplicates and reorder. Ask contributors to label or place their picks by mood so the quiet songs do not land in the middle of the night. Give the guest of honor a larger share, or a veto. Across 8,252 birthday inquiries in our national booking network's dataset of quote requests, 86% of requested event dates fell on a Friday or Saturday, so your guests will likely be coming from work or a busy day and will not assemble a playlist at the curb.
Decide in advance who holds the phone. One device, one person in charge of the queue, and a rule that requests go through that person will prevent most arguments. For group decisions that go beyond music, such as which neighborhood to end in, the polls page is a quick way to collect votes.

Ordering the night and keeping the music playing
The tool splits the queued songs into three blocks: about a quarter for warm-up, about a fifth for the ride home, and the remainder for the peak. The reasoning follows the shape of a night out. On the first legs people are still arriving, greeting each other, and talking, so songs they can talk over work better than anthems. Between venues, energy is highest and the songs everyone knows the words to belong there. On the ride home, the group is tired and slower sing-alongs fit the mood. Build the playlist in that order and turn shuffle off.
Then protect it from the two things that stop music in Chicago. The first is signal. Streaming drops on Lower Wacker Drive, in parking structures, and sometimes in the dense blocks of the Loop, so download the playlist for offline play before pickup. The second is the connection. Sound systems differ from one vehicle to the next. Some use Bluetooth, others an aux cable or USB, and a newer phone may need an adapter. Ask how phones connect on the assigned vehicle, bring the cable, and carry a charger.
