A quick tip to keep track of your mp3 you bought in Amazon.com if you are using iTunes. On a Mac, by default, it imports your downloaded mp3 to iTunes, nice, but it does not create a specific ‘Amazon.com’ playlist to easily find them, like the ‘Purchased’ you have for titles bought on the iTunes Store. Since they are not doing it for you…DIY (Do It Yourself!):
1. Each mp3 from Amazon contains a comment with ‘Amazon.com Song ID: xxxxx’ (xxxx is a unique key per song I guess).
2. Create a smart playlist with in the comment containing ‘Amazon.com’
Done!
