need some relaxing music for work-time listening

I used to listen to things on the order of german speed techno, effectively as a caffeine supplement to help wake up and stay that way.  I’m wondering what it’d be like in the reverse, though.

I’ve got a few albums (yes, including Yanni… I’ve had it since NCSSM) that qualify, but I wonder what others listen to (for those that listen to what they’d consider to be “relaxing” music).

I’ve had a couple co-workers swear by various forms of soft jazz or relaxed classical, and I fully agree it would need to be something without actual words (I find those too distracting, as I end up trying to listen and follow them).

Any recommendations?
