I don't dislike Hotel California through it being overplayed, I dislike it as I've always found it really boring.
I had stopped listening to the radio for years until I decided to give local college radio a go in the car. Have discovered countless bands I'd never have heard of otherwise, most of them local. Shazam has been my friend in capturing the songs I like.
For me BBC 6Music is a shining beacon. So much of the stuff I pick up on is from various shows on that station.
