I only recently discovered how very useful these links are to help finding good and reliable tags for genre, style, year, musicians, etc.
But you'll often have to consult several websites (allmusic, RYM, wikipedia, lastfm, discogs, etc.) before finding and deciding on the best information.
Also sometimes you want to search for a song, and other times for an album, or a work (classical). This also means an increased amount of required links.
So I would definitely appreciate and use the option to have more links available.
