Songer is great but you know what would make it even better?

1) After generating the initial song, have the ability to change the tempo before exporting. Also have the tempo stated after the generation is complete.

2) After generating the initial song, have the ability to change the KEY before exporting. Also have the original KEY stated in the details section. Same with the original tempo.

3) Option to export stems DRY and NO EQ so we can mix them as we see fit. Give us a with or without FX option!

4) Have your AI mastering tool render these at -8 LUFS so they can be put on a CD!
