The numbers presented next to each album title are the weighted average rating, and, in parentheses, the raw average and number of ratings (out of 31 included sources). The weighted average is based on a formula ((Y-21)*(1/3)+X) that includes the raw average of ratings (X) and the number of sources that have rated the album (Y).
The magazines I used for the ratings were:
EUR + Australia: Dansende Beren; Gaffa-dk; Gaffa-sw; Humo; Jenesaispop; Laut; Mondosonoro; Musikexpress; Nojesguiden; Ondarock; Plattentests; Sentire Ascoltare
UK: Clash; DIY; God Is In The Tv; Load And Quiet; Music OMH; NME; The Guardian; The Line Of Best Fit; The Skinny
USA + Canada: Allmusic; Beats Per Minute; Exclaim!; Nothern Transmissions; Paste; Pitchfork; Popmatters; Rolling Stone; Spectrum Culture; Under The Radar
Highlights: Rob makes the top three songs from the album according to Allmusic, Consequence of Sound, Jenesaispop, Plattentests, The Skinny, etc…
