There is no direct footprint benefit because each JVM still has a copy of the AOT executable but there are memory and CPU savings from being able to reuse this code rather than repeat the compilation.

And I repeat again: These two USES of the law are in direct contradiction to each other.

Features - search, repeat, random or shuffle play-back, FM receiver, format compatibility, ability to feed songs through a home stereo, and direct recording capability are some features to consider.
