What you are going to want to do is boost the artist field with respect to the
others, for example using edismax my 'qf' parameter is:
number^5 title^3 default
so hits in the number field get a five-fold boost and hits in the title field
get a three-fold boost. In your case you might want to start with:
artist^5 album^3 song
Getting these parameters right will take a little work, and I would suggest you
build a set of searches with known results so you can quickly check the effect
of any tweaks you do.
