iLuvMozart just got updated today. It claims to enhance music quality by a factor of 4x. I check it by winrar and find down it is now 128kbps. One interesting fact is that all the songs in extra package ( you have to buy for $10) are downloaded and we just simply use winrar to extract it. However we cannot use them with the app. For people that don't know this app, it is a collection of famous classic song composed by Mozart, Beethoven, Bach... App provider intends to use those music to boost IQ.
