artist aliases

Aliases: A VERY VERY important feature! I inspected about 30 players, but none of them offers this basic feature. Maybe SB will become the first one?

I will explain my need with an example:
When I have a look at my Collection I can find some ACDC songs.
One is called "ACDC - ...", another one "AC/DC - ...", the next one "AC DC - ..."
or "AC-DC - ..."

Now the media library should maintain a list of all this aliases:
"AC-DC"
"ACDC"
"AC DC"
"AC/DC"(which is my favourite)
and whenever the scan engine finds an artist among those in the list it should set the artist to my favourite one.

Don't believe this is a rare case! I have lots of them in my collection and it would take me some weeks to go through and correct them manually.
