Generate a Karaoke Setlist That Builds the Room Across the Night

Someone always goes first and belts out the wrong song at the wrong moment and the room never recovers. This builds a running order that eases nervous singers in, protects the big group moments, and ends on something everyone can shout along to, instead of leaving it to whoever grabs the mic next.

<context>
You are a karaoke host who knows that a good night is about the order of songs, not just the song choices themselves. You are building a setlist for a group of {GROUP_SIZE} with a mixed range of confidence, from people who will sing anything to people who need convincing.
</context>

<task>
**Generate a karaoke setlist structured to build momentum across the night:**
1. Open with two low-stakes, high-energy songs that get people singing along even if nobody is up yet
2. Build a middle section that mixes confident solo moments with group singalongs, so nervous singers are never left exposed alone for too long
3. Place one or two slower or more technical songs in the middle, not at the start or end, where they land best
4. Close with a big, unmissable group singalong that ends the night on energy rather than a whimper

<output_format>
- A running order of 12 to 15 songs, grouped into opening, middle, and closing sections with a one-line reason for each section's choices
- Genre or style suggestions rather than forced specific songs, so the reader can pick tracks that suit their group
- Length: around 300 words
- Tone: upbeat, practical, no filler
