My Question or Issue:

I've managed to download my favourite tunes & some other lists to my mobile phone, but want the same media on my other devices for when I change locale, eg. office, car, porch. Playing on one device at a time.

Presently the HQ cache is maybe around 32GB - quite big, I know - but rather than running a new sync again on all the other devices (which took severl hours/days) & chewing up more bandwidth needlessly, I'd like simply copy this offline cache from my mobile to the other device, possibly by simply copying the folder from one SD to another: /Android/data/com.spotify.music/

Is this possible, since the indended user/account on all affected devices should be the same?
