A better way to download aac is to buy it in itunes store. It has high quality and complete functions, but the price ... I usually go to lossless music forums such as chop suey music forums. The disadvantage is that search is not supported. Songs are downloaded through the network disk, which is very timely. I haven't found any quality resources for the time being. I'll let you know when I find it Of course, you can also download mp3 320k files and convert them into aac, so the sound quality has not changed. It can save general capacity to ask: Where is mp3 320K? Answer: Cool dog, the premise is that you can tell whether it is 320k quality, not whether it is big or not. Q: How? Answer: If you are not a professional, you can't tell the difference between 320k and 192k. I can only tell the difference between 128k and 256 (or 320k). It's okay. In fact, some of them are psychological, not downloading any music, just browsing. If you have any good music, you can go to the zasv forum, where there are 320k albums, high-pitched aac and lossless albums.
