I listen to music 3-6 hours a day and am the type of person who doesn't enjoy hearing the same song the same day or really the day after. Sites I've used for discovering new music were reddit and rateyourmusic.com.
Beyond that I do use Spotify song radios, but typically the song has to be far outside my standard genres to show me new music.
I've discovered more music new to me on Radio Paradise the last few years than anywhere else. They stream up to FLAC quality so an excellent choice for listening on the home stereo.
