"June Gloom" is one of Beck's Planned Obsolescence DJ mixes that was on beck.com. It went up on June 18, 2010, after a couple of months without a mix. It is one of Beck's longer mixes, lasting 65 minutes. Because of the length, a larger portion of each song is used than the usual snippets of past mixes. Also I get a sense he mixed vocals from one song with music from another a bit more than he usually does.
Many of these songs more or less seem to be, or come close to, the genre of "slowcore" (especially the first half). That kind of fits the name of the mix--June Gloom is the name for the morning fogginess that envelops southern California during June. There's also a bunch of summer themed songs in there.
