Just to add my tuppence
Being a recent convert to the Android fold (brand new GN - still awaiting update
), and having used iTunes/iPhone for too long, I felt the need to find an app that would let me sync iTunes playlists.
I tried a shed-load of apps; doubletwist was pure crap (IMHO) and not worth the effort, WinAmp might "really whip the llama's ass" but didn't "really know how to sync a playlist" well enough to warrant me keeping it.
I then found iSyncr and the WiFi plugin and these did
exactly what they said they would, seamlessly and effortlessly. The free version would only sync 30 tracks per playlist so the paltry price they were asking for it seemed worth it to me.
As for the Google Music point... not available to UK users yet but there is a very simple workaround, just waiting to set this up on my phone.
