Hey, Grooveshark dev here...neither I or a couple other devs I just asked can think of a feature that we removed related to radio. Can you give some clarification?
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.
Oh I see what you're saying now...to my knowledge we never had a feature like that, unfortunately I think it would be fairly expensive to implement the way our data is structured right now (it's optimized for looking up playlist -> songs not the other way around), but I can definitely see the appeal of a feature like that. I could see us precomputing a list of playlists to check out per song and applying some quality metrics to them...precomputing would preclude us from being able to do looking up playlists by multiple songs. Anyway I will mention it to my boss, can't make any promises of course.
Talking about the way Grooveshark structure their data could be an interesting topic.
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! ;)
