Weird. As an anecdote my "Daily Mix 1" has 50 songs, and only two bands I didn't recognize. 62% of the songs are by artists with more than one song in the list. The most songs by an artist? 7 songs over 3 albums. Of the 50 songs, only 4 were put out this decade, only two bands did I not recognize. "Daily Mix 2" is better with 30 bands, with the top band having 4 songs across 2 albums. Coincidently 62% of songs are also by artists with more than one song in the last, but the most common artist only has 4 songs across 2 albums. 19 unrecognized bands, so that's something.
