How about some Britney, or Aguilera. Or even better, the pre-hair cut Michael Bolton ?! Haha :)
Nah, seriously, I would enjoy some older stuff played. I just reviewed some old music I have of bands like Neon Judgement, The Young Gods, Die Krupps, Revolting Cocks, PoÃ©sie Noire etc and would love to hear much such as this. DG plays a lot of new music and I've found a lot of new bands to listen to through DG. But, it's also quite nice to rediscover good music that you'd forgotten you liked once. Also makes you recognize a lot of influences in contemporary music. DG just played Cesium 137 - The Storm and to me it just sounds like Human League. Anyhow, I'm not suggesting that mixing the content even more might be a good way, but I do think a lot of listeners would enjoy "themes" once in a while. E.g. play a certain type of music every other Friday. Just my $0.02.
