Doug, don't feel too bad. I've been there and experienced the same MANY times over myself. Music is a lifelong path of discovery and we can only master a bite at time. Take the time to taste all the various entrees on your plate and eventually you'll have enjoyed a thoroughly satsifying meal. I often face stumbling blocks when faced with a particularly challenging song project, but find that by letting it go temporarily, and working on some other aspect of music, from working on another song, or other aspect of music making, or even listening to a music CD, or going out to see music performed live) can provide added perspective & inspiration for you to come back and work past your current slump. Doug, rest assured that your feelings are normal. Don't give up on music.
