Music Collection was paired with the music room and provided five hundred albums. A fairly wide range of music to be sure, but the nature of it was what was causing Survey to struggle against her commitment to stay with the mirror, and also deploy as many sensor drones to the room as she could fit.
Like with the last major infusion of media from the Personal Reality constellation, the provided albums had the particular property of not being from our universe. From what I could gather from browsing Survey's initial reports, the majority were from the same world as the books in the Library. Everything prior to the appearance of Scion was identical, with diversions becoming more drastic as time went on. Nearly thirty years of cultural drift, captured in musical format, with each album accompanied by a wealth of information on its creation.
From what could be gathered, priority had been given to the most popular albums. Best selling records led to a fairly diverse selection, with everything from major releases, best-of collections, holiday albums, and even movie soundtracks. Altogether it served to fill in a lot of blanks in the picture the Library had begun to paint.
The collection had music from the capeless-Earth, but it didn't just have music from the capeless-Earth. Scattered among the collection were occasional albums from the worlds of my powers.
It was a selection even more varied than the collection from that other Earth. There was a collection of Klingon opera, a CD from a boy band called the Achieve Men, a collection of 'the Best of Mahogany Hall', a full concert performance by 'Lynn Minmay', a self-titled album from a group called Priss and the Replicants, a country album from someone named Cherlene, a collection of astartes battle hymns, a longform performance of 'The Storm King' that came on a stack of phonograph records that stood three inches thick, a rap song about mole rats, a memorial album for someone named Kanade Amou, and a surprisingly wide sampling of alien music.
Honestly, I wouldn't have minded the chance to dive into the collection, both the conventional and fantastic, but we were on a schedule. No doubt Survey would have everything cataloged and backed up well before the next time we entered the photonic core for training.
