HY is an extremely popular Japanese pop/rap rock band that first formed in 2000. Since their formation, all of the group's albums
broke the Oricon top 10, and starting with 2003's "Street Story", all of the band's albums impressively reached the top of the
charts, with the lowest-selling album within this era being 2008's "HeartY", which still reached number 2. This decade-long
period of chart-topping albums easily makes HY one of Japan's best-selling and most memorable bands of the 2000's.
