What Could Have Been: Both Nakanishi Yuuka and Deguchi Aki were AKB 4th generation research students who transfered to SKE when Team S was formed.
Team E's Kito Momona auditioned for Morning Musume's 8th generation, but failed.
Team E's Miyamae Ami auditioned for AKB's 12th generation, but also failed.
SKE also has their own Request Hour, but it is composed of 50 songs instead of 100 (although it was composed of 30 in 2010 when it was first celebrated). Fans can choose both original SKE songs and AKB songs covered by the girls in their stages.
"Kareha no Station" won in 2010 and 2011.
"Hazumisaki" won in 2012.
"Anata to Christmas Eve" won in 2013, making it the first time a non-original SKE song tops the list.
