Aliases probably need some further tweaking to enhance the discoverability of some of the most common labels in the database.

For example, if we search for "EMI" [1] we'd expect to find EMI Records [2], which has the exact match as an alias, as the first result, but we can see that it lies at the end of the second tier, as if it had no such alias.

On the other hand, some aliases produce equally weird effects by pushing unrelated labels to the top: if we search for "BMG" [3], we inexplicably get "Ariola Benelux" as high as "Bertelsmann Music Group", because of the "BMG Ariola Benelux BV" alias [4], which should definitely get less weight.
