Q: I cannot download from the cloud

Please point out my stupidity. I am in the process of trying to sync my library via iMatch but given a couple of problem songs, I have not completed a full sync. In the meantime I have noticed that when not on wi-fi, I can only play a limited number of songs on my iphone. When I go into the music app, there is no option either on wi-fi or off wi-fir to download music back on to my iphone as there was. I recently deleted songs locally from my phone to free up disk space.

This leaves me having payed for iMatch and I need to continue to resolve, but I cannot play off wi-fi, previous purchases and what has sync'd to iMatch. I want to download songs from the cloud back to my phone.

I know I'm missing something obvious!
