This 2017 Demon/Sony Music European 5-disc box is not the strongest of the many 70s’ box sets that are listed on Amazon (so 4 1/2 stars), but it is non-the-less filled w/a lot of good Brit-leaning music (especially the rock tracks). Disc 1, 68 minutes, is Brit-rock & glam; D2, 70 min., R&B & Disco; D#, 63 min., soft rock & R&B; D4, 66 min., R&B & Disco; D5, 70 min., is a mix of genres (w/6 tracks that are on other box sets). I am amazed at how good the R&B & disco stuff is now – back in the 70s I hated it (but then again, I like a ton more stuff now in my late 60s). All tracks are original charting singles (but not all in the U.S.). Quality of sound is great (re-mastered??), & playback levels are quite even. There are a few minor song title glitches w/Windows Media Player. Song title/artist/composer/label/date are listed on each inside flap of the 5-fold cardboard case – title & artist listed on back cover also. Each disc slides into separate open-at-each-end slots & are very hard to slide out – I used a large eraser on the end of a pencil.
