Missing purchased songs from iTunes
Hi, recently I have been using Music and I found out that some of my purchased songs were missing from the album list, I have tried deleted all local documents and downloaded them again, but the files still didn't appear. When I went back to the album and songs that I have purchased from iTunes, it showed that I have purchased but still I couldn't play the whole song (like a one minute trial listening same as usual); also I have been to App Store to check whether I have hidden any songs from the macbook, but I didn't. Is there a way that I can recover the songs back? Thanks!!!
