Thank you, I will be keeping an eye out. I actually found out how to do it, which is by composing a url like this: http://developer.echonest.com/api/v4/song/search?api_key=LQPMNB3ATFB3STGYV&format=json&results=10&max_tempo=132.31783333333334&min_tempo=130.31783333333334&max_loudness=-8.029527777777778&min_loudness=-10.029527777777778&artist_start_year_before=2013&artist_min_familiarity=0.8&song_min_hotttnesss=0.8&max_danceability=0.813064888888889&min_danceability=0.41306488888888887&max_liveness=0.3633145&min_liveness=0&max_speechiness=0.3485875&min_speechiness=0&max_acousticness=0.35331783333333333&min_acousticness=0&mode=1&key=5&style=hip%20hop.
I'm not getting any songs from this kind of query, do I have to increase the range of my parameters or are there simply too many to begin with? I've played around with it myself but it seems that you have to get much less specific which is disappointing.
