Album: Remove UserName and GroupTitle from PageTitle

Hello.
Can you please give me some advise?
Ath the moment Album pages has this titles (in browser):

1) "Username - Albums - Album's title"
2) "GroupTitle - Albums - Album's title"

I would like to remove "Username -" and "GroupTitle - ":

1) "Albums - Album's title"
2) "Albums - Album's title"

or move it after albumtitle:

1) "Albums - Album's title - Username"
2) "Albums - Album's title - GroupTitle "

What do tou think about this? I supposed, it would be better for SEO? But lots of "Story album" (withut Username) is a bad idea?

Anyway if there is no any option, can you please give a hint, which files need to be edited? I'll try to do something...

Thanks.
