Yeah. I don't think this sudden rush of the album will affect it much. The songs are already written, she probably ahs like a ton of songs never released and planned for this album anyway, maybe she felt that she had such good songs that she didnt want to put them on hold for the next single release around February or so, and wanted everyone to hear them sooner... It's still a month left 'till the release, and Im sure there will be more than enough time to record those new 4-5 songs, and finish it off
