A guitarist I know told me thirty years ago that people want to hear the song they got laid to the night of the prom, or their song that was "their" song in high school. And for the most part, I've found him to be right. We as musicians, especially "on the bus" musicians, tend to develop a myopic perspective that makes us think that music and it's interpretation matters to the general public, when that trip is really for our steps alone. Most of our other musical stylings (originals) are for other musicians, and few of them are important enough to transend the moment.
To those of you who would like to get your songs out to reap the benefits, I can tell you that it is who you know, and then it is a long battle. Thousands of demo tapes are submitted almost daily to record companies, artists, etc. The majority of them are never listened to. A lot of that has to do with legal ramifications (Hey, he stole my song), or just that the sheer volume of submitted material leads to a jaded approach to the tunes. And the record companies would rather go with a known writer (union) than you. I used to be in the business, and it is unfortunately rare that a JJ Cale will come along and have his demos succeed. If you know someone in the industry who will genuinely listen, critique, and submit your song to an artist or manager, it would still have to pass the artist's critique and find it's way to a recording and then hit. The old days of shopping your recording to radio stations is gone (most radio is centrally formatted now), or landing a helicopter in the artist's yard (Kris Kistopherson successfully did this to get "Sunday Morning Coming Down" in front of Johnny Cash) are pretty much gone. It's a tough business.
Make music for your own enjoyment. The rest of it is a lot of work and disappointment for most likely little reward. If you DO hit, though, that's where the money is in the music business. Songwriting. Good luck, and if I can help with advice, etc., call me at 720-389-7137. I'll be unavailable though until after Sept. 2, as I'll be returning to Virginia for about two weeks starting day after tomorrow.
Gone are the days we stopped to decide where we should go, we just ride...
