Sequencing your record can be one of the most unexpected troubles you can have making a record. One of the biggest mistakes I see young bands make is they come in with a list of what the song order should be, without ever having listened to this order. In this day and age of DAWs and iTunes playlists there is no reason to ever do this. Many times when a band comes in with a list I ask them to give me a minute to play with the sequence. I load all of the songs into my DAW and move songs and how much they overlap with each other around till everything feels good. This usually results in the group being much more happy with their order with a lot less guess work. The way song’s keys blend together and the moods are very hard for most people to conceptualize, instead use your ears and your emotions and listen back to how they blend together and you will make much better decisions.
