The spots are available from November and apparently can be tailed to suit the sponsor. Specific music genres or themes can be built into the sets or branding can be expanded above ground or linked to other media activity.
Donna Price, from CBS Outdoor, told Media Week it offers the chance for clients "align their brands with music culture and to play their part in brightening up journeys for passengers".
It would be great to see some imaginative sponsorship of these sites and I wonder if one brand will take it on or if it will be open to many?
A while back there was talk of labels experimenting by getting buskers to play certain songs. Perhaps something could be introduced where even commuters can decide what they'd like played at each station.
