JMHO but I think the decade channels should be a true Top 40 (or for me a Top 100 since I love obscure music) and then have specialty channels for other genres. I love New Wave (and boy do I miss Fred, Ethel and Lucy on XM) and I really enjoyed Top Tracks on XM as it was rock from 1979-1991 with non of the soft AC stuff. I grew up on MTV and many videos that I remember just never made it on the Top 40 chart but I still remember the songs. This is especially true of the New Wave and Heavy Metal formats. I like hearing more variety on the decade channels.
