On a more serious note, musty smell most probably comes from the album pages.
I agree: if the stamps have low value, do not waste time and dispose of the album.
The alternative is to individually remove the stamps from the album and put them in a stamp stockbook. This works best when the smell is caused by smoke as at least 90% of the smell retention came from the album pages, not the stamps themselves. By transferring the stamps to a stockbook you eliminate at least 90% of the smell.
Good Luck
