What has worked nice for me is to listen to the AccuRadio channel of the genre I’m in the mood for, and rate the songs. Then later when I have the time, I look at my ratings history page and download the ones I rated high from youtube in mp3, so I can have my own local “radio stations” of the songs I enjoy. Then months later, when/if I got bored of them, I can go back and come across new ones on AccuRadio.
