Last.fm's artist MBID can point at the wrong same-named band (it mapped
"Looking Glass" to an Australian stoner band, not the US pop group), and the
/lastfm rows trusted it verbatim — so opening/following grabbed the wrong
artist and the grabbed album never showed on the artist page. Now open/follow
resolve via MB search: resolveArtistChoice keeps candidates whose name matches
exactly — 1 match is used directly (even over a disagreeing Last.fm MBID), 2+
surface an ArtistPicker showing each MB disambiguation ("70's US pop group,
track 'Brandy'" vs "Australian stoner rock") with MB's top hit flagged
Suggested. Core decision logic unit-tested; no worker/schema change.
