I like to use the time filter and can listen in 5 languages; “oldies” in various genres, times, and places, isn't that hard to research--plenty of free internet radio out there.

Sorry to the new bands out there.

Edit: Also I find the mindset of finding the exact best music is kind of unhealthy. Building a tolerance for meh actually helps me discover things that don't immediately and instantly appeal to me, and I think that leads to more musical variety in the long run than the skip-happy attitude streaming encourages.
