I just realized that in the "Get Info" option for a song in iTunes you can go to the "Options" tab and adjust the volume of a song. I'm not sure how long this has been here, but after buying The Pussycat Dolls - When I Grow Up from Amazon MP3 I wanted to lower the volume since it sounded louder than most of my other songs. Problem solved. And I love Amazon MP3. Easy to use, high quality mp3s and a new special deal every day. Plus every Friday they have at least 5 $5.00 albums. Amazon Special Deals.

Amazon recently unveiled Amazon MP3. They have 2 million songs, and popular songs are discounted from $0.99 to $0.89. Unfortunately they do not accept Amazon.com gift certificates to buy those songs. This is a major flaw and one that they will hopefully fix in time. Usually 1-click ordering lets you choose to use a gift certificate, but with Amazon MP3 you can only pay for your songs with a credit card.

But it is beta so they could be holding off on it for a while. It also took iTunes a while to offer gift certificates, so it could be a legal issue. But Randy reminds me that you can't buy Amazon gift certificates with a gift certificate balance, so it could be a flaw in their system design. I find I have a lot more Amazon certificates than iTunes, so it would be a perfect solution to be able to use them.
