Really interested in subscribing to iTunes Match. Most important reason is I want to stop having to keep over 400 songs on my iPhone (to free up some space). 1. I have songs downloaded from a variety of places in which I have manually added album art, artist name. Will iTunes Match be able to find matches based on just the artist name and song title? 2. When I enable iTunes Match on the iPhone, does it automatically download the songs (that would defeat the purpose of having them stored in the cloud)? 3. I assume my library on the Mac will not be impacted.
