I recently took my iMac to Apple to resolve a number of issues. Apple were able to solve the problems but (with my permission) had to wipe the hard drive. As all of my music is stored on iTunes I didn't have a problem with them doing this. However, obviously none of my music is now on my iMac and I can't figure out how to get it all back. It still exists in iCloud and I can listen to any of it on my iPad or iPhone. How can I get all my music back on to my iMac? Thanks
