What I want are people with taste kinda-sorta like mine to tell me, Hey check this is out, and pass me something not like everything else I listen to, yet somehow in the realm of stuff I might probably like.
My hack was to search for playlists containing a song I liked. So I would find a "rock" playlist with lots of songs I knew but a couple very good ones I didn't.
As a startup idea, I was thinking of a "Github for playlist". Basically, abstracting the different "streaming" services and really focus on the quality of the playlist.
Anyone could fork your playlist, add a few songs, and do a "pull request". The cool thing is how I could be subscribed to your playlist and since I trust your taste, I would get notifications when you add or accept new songs.
I see some kind of hierarchy where there could be "stable" playlist that are updated conservatively but also other "unstable" playlists where it changes often so you can discover more song.
That would definitely be a service I would use by following other good playlists but also curating mine and welcoming suggestions from friends.
bop.fm of YC S13 is doing exactly that. Their UI is way too clunky for me to think about using it yet, but the idea is solid
But all I want is to view playlists containing a song I like.
So, let's say I search for "One Metallica". I'd like a button "Playlists containing this song" that would let me browse playlists of everyone who has "One of Metallica" in it.
And, if I may suggest a new functionality, what would be even better is to find playlists containing multiple songs.. So, "Please show me some playlists containing the song One Metallica and Pull Me Under of Dream Theater". I'm confident that these playlists will contain songs I like.
Personally I preferred that way to explore new songs instead of the radio thing.
I would be surprised to test how much time it would take to find some playlists containing a song even with a trivial algorithm. The reason I'm saying that is that it would be very fast for popular songs to find a few playlists (We don't need 1000 results, just a few is great for our case). And for the less known songs, I'm happy to wait for quality playlists! ;)
In theory Pandora can solve that problem, but for reasons I don't know even their list-similar-songs-service is blocked outside the US (it used to be that you could use that one alone in a separate page, but then they blocked it).
They won my affection when they made a station devoted to the music of Breaking Bad to celebrate the start of the final season.
When I go, I get a message saying: Som følge af høje driftsomkostninger, har amerikansk baserede Grooveshark stoppet [blokeret for] adgang fra Danmark. Vi vil savne dig! Du er velkommen til at skrive til os. Vi kommer tilbage!
Roughly: Due to high operating expenses, the American-based Grooveshark has stopped [blocked] access from Denmark. We will miss you! You are welcome to write to us. We'll be back!
It uses embedded YouTube videos, but it's nice to use it on some occasions.
