I listen to alot of jazz, and there are several songs I am familiar with that I've listened to for years on my Sennheiser HD600s(HiFi headphones). These are the songs I use to tune stereos. When tuning, try to use an audio CD(not an MP3 CD) that has been burned with high quality files or preferably an original CD.
