So we know the category "MP3" from Amazon-: you can find almost anything goes shopping afloat by Outfit and the quality of the songs is good. However, there is this ominous forced to register the device on which the songs are downloaded. I do not hope that in a few years is a problem with my purchased MP3 tracks when a new laptop, MP3 player or a new smartphone is pending. Hab finally paid for the title, so mine and I should thus (legally of course) can do what I want. Why is there this registry compulsory I do not know. Maybe someone has worked at this topic already nearer.
