Of a singer.

Sang Jian (Song ってた) originally wrote "Song ってみた" in Japanese, meaning "I tried to sing". As soon as translated, it is obvious that this refers to an act, not a singer like China now.

"てみる" means to give it a try, which is also a common writing method. Usually, it won't be written as "てる". I translated "Song ってみた" into "Song ってた" with a far immature translation software at that time, and it became what it is now.

See for details.

Dancing is "ってみた", which means "try to dance".

The origin of song and dance

These two words come from two columns ("Song" and "Yong" respectively) on the Japanese niconico animation website, and the UP owner (contributor) submits his cover works or dance works to the corresponding columns.
