gonna shout it through the mountaintops

Which of my neighbors and car-drivers of McGuinness could tell I was only listening to this song over and over for thirty minutes:

This song is the best. It's the best song in the whole world. All the soloists but especially the "main girl" whose voice "is really crazy" and "does fancy stuff" really kill it. If I could have any music-affiliated wish, it would be to sit in on the recording of this dope jam, or to have the original girls sing it for me in a middle school-style concert.
