Don't believe everything you see or hear on Apple's iTunes Music Store (iTMS) – sometimes the previews and music don't match.

Browse for Seventies on the UK iTMS, and find the eclectic 3-CD collection. Click on Spark's This Town Ain't Big Enough, and you hear Lynyrd Skynyrd's Free Bird. Status Quo's Caroline sounds very much like The Temptations' Papa Was a Rollin' Stone.

Best of all is Barry White's You're the First, The Last, My Everything. Click this to hear the distinctly un-Barry Laughing Gnome by recent heart-scare victim David Bowie.

In the interests of Macworld readers and iTMS users everywhere, Macworld downloaded what should have been The Jackson 5's super ABC, but what we actually got was Free's rather lame My Brother Jake. We hope to get our 79p refunded.

One Macworld reader purchased Bach's Violin Concertos, only to find that the first four movements were clipped to about 40 seconds each. The iTunes Music Store refunded the £7.90, stating that: "While we expect a quick resolution to the issue that you have reported, please wait at least two weeks before repurchasing this title."
