It sounds like you are asking for a perfect audio version of something that is being broadcast by radio. If you want particular music, mp3 downloads are the best way to go. Recording stuff from the live radio will always be what it has always been. Prone to interference and abnormal noise.
I use my fuze a lot for playing back a 4 hour nationally broadcast radio show, that is on daily. I would never consider using the fuze as the recording device, even though it probably could do it in a pinch.
I have a well regarded 1980’s era stereo receiver with an outstanding FM section connected to a nice outside antenna. This receiver is connected to one of my computers, where I have installed a great software recorder that incorporates a timer function. Painlessly and automatically it records this radio show in great fidelity daily with no input from me. I even have the option of automatically encoding this recording to my encoder of choice…again without any input from me.
Nightly, it takes me all of 30 seconds to tag the audio file and transfer it to my fuze…and it always sounds wonderful.
I do have the option of downloading the same radio show (for a fee) at the host’s website; but they only offer it in a very highly compressed mp3 format. My off-air version sounds 100% better and I don’t have to pay someone to get it… (other than the investment of the recorder software, which I would have purchased anyway).
For every task, there are multiple ways in arriving at your goal. I’m not saying my method is for everyone…I just know it works great and is right for me…
