The seven hundred and fourth album: #704 Massive Attack - Blue Lines
There's a chill feel to this album - Unfinished Sympathy is the one I recognise best of those, but there are others in a similar mold. It's electronic music with an R&B vibe, some light rap and relaxing enough that you can have it sit in the background. It's interesting, a bit dreamy, but with enough to catch on to, just some nice and lovely easy listening music with a bit of substance.
