Since Rocks Off bought a smartphone this past January, we have downloaded almost 400 songs from iTunes. We know, we need help. But we have become fascinated with the damn thing.
One of the features we like the best is "Listeners Also Bought" at the bottom of each album's page, which we assume ranks the Top 5 other recordings people who bought that album also purchased. It's a good way to gauge how popular and influential an album has been, and where it ranks within the artist's catalogue.
Under someone's most popular records, for example, the LAB list is usually similar artists whose work was popular at the time, while albums a little further down the artist's totem pole tend to get bought within the same catalogue. Also, every last man, woman and child with a smartphone apparently owns a copy of Led Zeppelin's Houses of the Holy.
