I haven't been getting duplicate songs but the same artist many times.
Same here. I've often started up Radio Mode using a Metallica song and then listened to a steady and almost predictable progression of Metallica->Megadeth->Marilyn Manson->Metallica->Megadeth->Marilyn Manson playlist. Even this wouldn't bother me so much if it didn't seem to target the same 3 or 4 albums. Between just those three bands I have around 30 albums, so why it sticks with the same 3 or 4 seems a little strange.
Although not as strange as last night's choice. I once again started off with a Metallica song and it then played Megadeth->Metallica (same album as song 1 so I skipped it)->Marilyn Manson->Willie Nelson. I couldn't help but laugh.
I guess I just really wish I knew what it keyed off of so I could help it a bit. Sometimes it does a remarkable job and other times it seems it seems like it's just being lazy. I mean I understand that, if you choose Metallica as a seed song, then Megadeth and Marilyn Manson seem like natural picks, but I have other metal bands in my collection, and like I said, even within those 3 bands I have a whole mess of albums to choose from. If I knew which fields it used and how those fields were weighed in its decision-making, I could make sure those fields are filled with accurate data or be more mindful of the data I put in them.
What would be really nice is if we could have some sort of options screen to tweak how Radio Mode picks its songs, not just create a subset of songs it can choose from. For instance, I may want it to focus more on picking songs that have a similar Intensity, of BPM, or Genre, or Moods tag. While other people may want it to weight Rating or Styles or Year more heavily. So having sliders available to us to tweak how it weighs its decisions would be really nice. But right now, I don't even know if it uses any of those fields to decide. Even better, let us define what tags it should use to formulate decisions and how to weight those tags.
I just feel like Radio is such a cool feature (I love Pandora for instance) but it just feels kinda half-baked right now. I've set up this powerful PC as an HTPC and tried to convince my fiancee to use it to listen to music, but because she doesn't want to have to think to hard about what to play, she instead just tunes into the satellite radio stations we get through Dish Network. I showed her MC's Radio mode and she got all excited until it started playing the same 3 bands over and over. I explained to her about skipping songs that she doesn't want to hear and that it will get better about picking new ones, but she just wants to listen to some music while she cleans up after me. So Radio mode pretty much goes unused.
