I set up iCloud match on my PC and iPhone 4s. How do I remove songs on my phone to buy more space for other things? Also, I understand that my iTunes library is matched with better quality versions in the cloud. How can I replace poor quality songs with these better ones?
iPhone 4S, iOS 7.1.1
See http://support.apple.com/kb/HT5637 for details on how to use iTunes Match on your iDevice.
Also, I understand that my iTunes library is matched with better quality versions in the cloud.
That is not quite true. When iTunes Match is able to match a song, it matches it to the version sold in the iTunes Store, which is in AAC/256 format. That may be better or worse than what you already have.
How can I replace poor quality songs with these better ones?
If you wish to replace your current version with the matched version, just delete the current one from your iTunes library and download the matched copy.
How do I remove songs from my device and leave it in iCloud?
