That was certainly true about the "Underground Garage" channel back when I had it. To me an "underground" station gives airtime for artists who otherwise wouldn't get played.It was great for the first couple of years. Then the programming became repetitive on my favorite stations. I was about to cancel when overnight they seemed to widen their playlists. After my road trip/vacation in April I dropped it. It slid back into the old ways. On the hard rock stations you would think they only had 50 albums to play songs off of. I dropped it.
The Beatles don't quite fit that criteria.
