Try this technique instead. Been doing it for a dozen years and provides exactly what you want to listen to, legally. The cost is around a sawbuck and buys a license that can last a lifetime and may include carry over rights to one or more new computers.
Simply, buy sound recording software for your computer's sound card. I use Total Recorder, but have no relationship with the company. With zero initial know how, one simply plays one or more songs on their machine (Pandora, Last FM, CD, Spotify, Rhapsody, MP3, vinyl, YouTube etc.) and records the music in a chosen format via the software. Afterwards, it is then possible to separate the song (s) into precisely what you want to hear, under file names chosen by the individual in single songs or in playlists. I use other software to record video, using the same principle.
Besides my wife, Total Recorder is one of the best investments I've ever made. YMMV.
