So, I got a request for suggestions from the community here.

I've been an android user basically all my life, and recently I've had a need for music. There's a long story here, but basically, Spotify is a no-go. I want to keep my own list of music files, sort them on PC, send them to my phone, and play it there. I do have means to get files I'm interested on, and playback devices and connections are no issue. So far so good.

However, the experience I've had has been lacking, because I'm missing an important step: Synching. I've been copying everything manually. Back when iPods weren't a joke, way way back, I used one and the iTunes <-> iPod experience was great. I could setup playlists on PC or restrict certain files, then have them show up on the iPod. Then playing and rating music a number of times on iPod and those stats would transfer and generate new playlists such as most and least played. I'm looking for something like that again. I don't need a complete seamless experience, and the synching operation doesn't need to be done by an actual music playback application either.

Can anyone help me with this? What mobile+desktop applications combos do you all use for music and do they synch up?
