We do a little change up every now and then, but mostly the older classics on wklt-98, Kalkaska, MI.
My personal preference while working? Jazz and Blues. However, I'll never get my crew to go along with it....
Our Chef actually requires that music is playing. For a small kitchen, that only has room for a kitchen staff of 5 + expo, we have a surprisingly diverse range of music tastes. We listen to pretty much everything from Heavy Death Metal, to 80's glam rock, to modern country, and almost everything in between. We even do a thing while we clean every Saturday night where we go on a "world tour" of music. We will start with traditional Indian fold music, then move to Scottish classical, and continue moving countries and continents every 5 or 6 songs. About the only thing that doesn't consistently get played is rap, although our Thursday morning / lunch shift always starts out with some 2pac, but rarely lasts long, and only gets playtime once a week.
In my kitchen we listen to my iPod on shuffle in the morning, turn it off, or very very low during service, and then switch to an internet radio station that plays "Deep and Soulful House" for our main prep hours between lunch and dinner. After that the night crew plugs in their music on a first-come-first-served basis.
My iPod has a little bit of everything; Slipknot, Michael Jackson, Trance, Dubstep, Celtic, Jazz, Offspring, Tupac, songs from Southpark, video game music... You get the picture.
Friday mornings start with my K-Pop playlist (currently 26 songs long).
I'm interested to know what stereo everyone is using. We're using a set of plug-in speakers with a subwoofer that our Saturday/Sunday prep-bot brought in after the nigh crew broke my iPod dock. You can connect USB or an Auxillary cable to the sub, which I'll admit is a splendid treat, after 8 years of low-quality ceiling speakers and cheap mini-stereos with no bass.
We use some off brand ipod dock / station that does the job, as we have a very tight (cramped) kitchen. It has a aux plug as well, so even if you dont have an ipod, you can plug up your phone / mp3 player into it and listen to whatever.
I am quite jealous of your sub though, although if we had a subwoofer I'm sure we would get constant complaints from the dining room about the music, I feel we already push the border at times.
