Every now and then I look back at my recent songs, mostly unfinished demos and think to myself, "I've got enough for an album's worth there". In the past I've just lumped all those recordings together, made a cd and cover, and that was that, I've moved on to the next song, and so on, until there are about 12 that I quite like, and the same thing happens, burn a cd, done.
Now, this is ok I guess, it's a good chronological record of my progress but I never listen to them and neither does anyone else, because they are basically an unfinished, rushed collection of unrelated demos.
One day, I'd like to make a proper album, something I'm proud of, something I'm comfortable giving to friends. It'll need to be professional sounding and have continuity throughout.
My question is, should an album have a common theme running through the songs? Or is it more important to just gather up your best songs, regardless of theme and general feel?
