The track doesn't even have to be well recorded, you just need to have a very detailed and involved understanding of the track. If you can distill a recording to its essence, you will be able to to use it effectively as a reference track. Find different versions, listen and find the differences in flac, mp3, vinyl, etc. Listen to them on multiple systems, headphones, cars etc. It is super important to understand that simply playing and listening to these albums/tracks won't work. Over the day I'll try adding a few more suggestions Bassnectar - Time Stretch (particularly the track bass head, it is simultaneously thick and thin, you can get an idea of how a system handles super low bass and how the horns cover and perform).Crash Test Dummies - almost any vocal track.Cowboy Junkies - Trinity Sessions (amazing recording, tons of dynamics).I like to test loudness by playing loud albums:
