Listen to the show to see whether your music would fit into it. I do have quite wide-ranging tastes, but some things just don't work for me. Don't be offended if I don't play your stuff. It's just that it's not to my personal taste and I only play what I like.
Send some music with a short biog that covers where you're from, how long the band's been going and how many members your band has to wyrdways@googlemail.com.
The music files need to be mp3, wma or wav, AT LEAST 160kbps. If the bitrate's any lower than that, it just sounds rubbish. PLEASE don't send FLAC or m4a. They're a pain in the arse to convert.
All music needs to be original compositions. I don't play stuff by tribute or covers bands. I don't care how close your version is to the original, if you don't write your own stuff, I'm afraid I won't be playing it on my show.
You may want to send me a CD of your album or demo. To be honest, that's what I'd prefer. That way I can rip to my own specifications. If you want to do that, e-mail me on mail@wyrdwaysrs.com and I'll reply with my mailing address.
