Absolute radio is ok, you can also choose Absolute 60's, 70's, 80's or 90's too which is pretty good (DAB or internet only though)
Other than that I go for BBC Radio 6 purely because you get alternative music on there rather than just chart tripe, again its DAB or internet though.
I tend to chop and change through the Absolute stations when i'm working, mainly 80's, 90's, 00's or Classic Rock, depending on my mood.
Mainly because they stay away from mainstream pop music, and because of the fewer adverts compared to other stations.
I have a new DAB radio system on my bench, but have found reception issues can be an absolute nightmare. I tend to know when there's heavy rain (somewhere) as the sound will just get ropier by the minute, and a few months ago we had builders using a jack hammer outside for a few days, and that was completely game over, no signal whatsoever.
When that happens the iPad has to come out and i use the radio stations on there, or just create a radio station on Spotify and let that play instead. Just pick a song from an artist you like and it will play similar artists from that era and genre, then play the original artist again every 7 or 8 songs, it's been quite good so far.
