When you get to this page, even though you don't know how you got there, why not make the breadcrumbs:

Home > Albums > Song Info for Songtitle

instead of just 

Home > Song Info for Songtitle

This would be more consistent with what happens when you click an album name from, say, the playlist pane, where the breadcrumbs become:

Home > Albums > Albumname

I'd also consider getting rid of the "Song Info for" part of the breadcrumb.  Once the hierarchy in the breadcrumbs is Albums > Albumname > Songtitle, it makes it pretty redundant.
