What CD or Music file YOU USE to test bass???

One of my favorite tracks is from Better Than Ezra's Deluxe Album from 1995.
Track 12 - This Time of Year, is 4 min with the first min just soulful vocals and acoustic guitar until the bass guitar and drums kick in with incredible power and detail.
Everyone I have played it for is simply blown away because they have no idea what's coming.
This entire alternative rock album is very good with great bass lines throughout.
Worth a listen if you're not familiar.
