Although finding a way to play an audio cd (not sure why I didn’t just get the MP3 since I don’t have a cd player and my macbook pro doesn’t have a cd drive lol) took a bit of effort and ingenuity, it was well worth it. The songs are soothing and peaceful, much more so than the midi-heavy songs built into my baby’s rock n’ play and swing. There is just something so much more tranquility-inducing about listening to real instruments. The guitar is gentle and soothing and the music is set to a relaxed-heartbeat tempo that also provides white noise. My toddler, newborn and I all sleep great with this playing.
