This is a really tough question! At my old job, I would open up in the morning and turn the store music on. Whoever was first could pick the Sirius XM station (I think that’s what the system was linked to) to listen to for the hour before we opened the doors and I’d always pick 50’s music. Every one of those songs that would come on would really get me so I can’t say what’s best. Most of that era was awesome!
