If you can’t download songs from a music site, then you can use the recording feature of iMusic to capture the audio. It is available to record music from radio stations as well. In a word, if you can play a song online or on your computer, then you can record it and save to your iTunes Library.

Click the "Record" button and prepare to record the song you’re going to play. You can open a web browser or an application on your computer to play the song you’re going to record. iMusic will detect the song and record it. During the process, the cover and artist for a record song will be added to the song automatically, making it quite easy for you to identify the songs in iTunes Library.
Tips: you can try the Record feature while playing songs in iTunes radio station, Spotify, BBC radio stations, and so on. It works perfectly.
