I love the iTunes match service and have used it since the day it was released here in the U.S. It was a little buggy at first, but that was to be expected. Over time, it became more stable. For music lovers like myself with libraries far larger than our iPhone capacity, it was a godsend.
But under iOS 6, the iTunes match service is severely limited. For example:
1. It appears that you can no longer delete songs from your iPhone. Under the old OS, you could delete songs and return them to only being stored on the "cloud." Now, it does not appear that you can delete songs to free up space. You can delete all local music. Just not easily. Please see posts above. You can do it from settings, and you should be able to do it by turning Match off then on. Not simple and easy, as it was before, but it can be done.
2. You can no longer download single songs from an album. Under iOS 6, you have to download the entire album. Ugh.
The way you could do it before was nice and easy. I agree. You can do it now, but it is not easy. You can hit the cloud button to DL an album and then quickly hit the "stop" button on the songs you don't want. Not the way I want it done, but it does work.....
3. The cloud icon is gone! You used to be able to easily see which songs were on your phone vs. only being in the cloud. Now, you can't tell! So, you may start playing a song, only to realize that it's stored in the cloud and now eating up precious data. This is a huge limitation that, IMO, takes away power from the user to manage data usage (yes, I know you can restrict downloads to only over WiFi, but still).
Anyway, some coverage of this issue would be great. I am hoping that if Apple gets enough pressure from users, it will push out an update that restores iTunes match to it's functionality under the previous iOS. I love my iPhone 5, but having iTunes Match limited in this manner is a huge setback.
