It's a quasi-show stopper for me. I have to iPod Classics that I use in the car, but they only have 41K of my over 50K library. I have the entire library on my phone, and I want it synced with iTunes, including playcounts, ratings, and last play time (both directions). iSyncr did that. I need livelists to duplicate my iPod Classic functionality. Rocket Player did that. The combination allowed me to have my full library on my phone.
Since whatever the changes at JRT, WiFi syncing over iSyncr is broken. USB works, but still takes over an hour, plus a Rocket Player rebuild, a reboot of the phone, and another Rocket Player rebuild. Now there is this problem with Rocket Player.
I've got queries out to DoubleTwist and Droid Transfer to see if they will sync the metadata, and will sync it in such as way that a player that supports livelists/smart lists and songs on SD card can see them (such as Gone Mad player). The world seems to love to stream music, but there are those who either don't have such data plans, or work in places where you can't stream.
It's a shame, because the combination was a reasonable one (not great -- I still believe they could have synced faster with proper coding). But it worked.
Now it doesn't.
