Hey all, Some really really great picks listed in this thread. I thought I'd add some of my own. I'm a live sound engineer and am fortunate enough to work with some of the best high end sound reinforcement gear day in and day out. Needless to say, I've developed my own (ever evolving) playlist over the years. Some tracks picked to tune, balance or even stress test PA systems from small to arena sized. Below are some of my current go-to's that I've not yet seen mentioned here: Tears For Fears - Badman's Song : A great live sounding mix with fantastic drums, dynamics and at times, a really busy arrangement that is nicely balanced. (the bass guitar playing is a hidden gem was well...) Lyle Lovett - She Makes Me Feel So Good : A fantastic mostly acoustic arrangement with some excellent vocals, both lead and background. Nice spatial placement of the instruments. Eric Clapton - Change The World : My opinion of a great sounding mix that is representative of typical pop compression and mastering. Infected Mushroom - Forgive me : My go-to stress test track. Very out front, heavily effected vocals, excellent tight low frequency energy, lots of wide panning effects. Depeche Mode - Policy Of Truth : A snare drum that just punches right through the center of the mix. Beck - Morning : The vocals, the vocals, the vocals. Nice low frequency heavy mix with high frequency features that really seem to float on top. Oh, and the vocals! I've got plenty more, but these are the tracks in heavy rotation for me right now. Love this thread! -jerm!
