When I search a song, I get a list of songs. In that list there is the song in the original album somewhere.  But it's between the results of that song in best of albums, all kinds of collection albums and karaoke albums... 

I would love to see the first result being the song in the original album it was brought out by the original artist. 

That also simplifies the liking of the song. Sometimes you like a song twice because it's on another album.
