i'd agree that it seems like the management that are mainly to blame.
i was talking to one of the weekday djs a few weeks ago, and they pretty much admitted that they hate a lot of the stuff they have to play, and wish they could play a lot more leftfield stuff.
obviously they can't play a show full of Sonic Youth or tUnE-yArDs etc., but they should have a lot more freedom in what they play.
there's only so many times you can hear KoL, Two Door Cinema Club or Ham Sandwich during the day, every day.
i think the playlist is a lot at fault too. there's some good stuff on there, some rubbish IMO, but the main problem is that things stick around on it too long, and are overplayed. you can hear some of the playisted songs 5 or 6 times from 9am - 5pm.
it doesn't help that a lot of them are generic bland indie-pop like The Vaccines or The Wombats.
i very rarely listen to Phantom during the day anymore. i listen to the Dublin City FM drivetime show which is on from 4-7 (which plays a lot of indie stuff that only gets played on the nighttime/specialist Phantom shows) , or Newstalk or mp3s/cds before that depending on where I am.not even going to start on the B.S. chat nonsense in the afternoon.
for dub radio that's where it's at. Give DubCity a text in and John Neary will normally play what you're looking for. They also give away 3 hours of parking to pretty much everyone so it's another plus point
