In the case of Fast as a shark inline work search, for instance we only see cover artists, because they are many, and we do not even see Accept, the original artist.
Original artists should be showed first then cover artists then writers.
And inside those two categories, maybe display in decrease order of how many.

Because the performer are easier spot from editors, it is the most famous info in most of the cases.

Examples:
1. inline work search big problem

A. Go to this cover and try to find the original song Fast as a shark by Accept in the inline work search. You will only see Fast as a shark by Helloween, Witchery, Altar, ... and no trace of the original Accept band, so you are not very sure to find the correct work.

B. Go to this cover and try to find the original song Alone by I-Ten in the inline work search. You will only see Alone by Warmen, Heart, The Shadows, ... and no trace of the original I-Ten again, so you are not very sure to find the correct work.

C. When we inline search 聖母たちのララバイ by 岩崎宏美 we find
聖母たちのララバイ by John Scott, 山川啓介, 木森敏之, ...
They are the work credits in random order (probably order of AR creations).

2. work search problem

B. Search for Alone work by I-Ten to have the explanation of 1B.
Warmen (cover perf.)
Heart (cover perf.)
The Shadows (cover perf.)
I-Ten (orig. perf.)
Syu (cover perf.)
Glee Cast feat. Kristin Chenoweth (cover perf.)

We should display orig. perf. / cover perf. / work credits in this order IMO.
