Custom hourly music with supported loop (via mp3, midi, or brstm files) that play a specific song you pick on the hour. For music files that don't support loop, there can be something you can find by finding it's sample # location. Similar to how brstm files are looped.
Custom (hourly) bell sound that may bypass the tone tune feature with custom bells that play a specific sound per hour. So if it is 1 pm, there will be an hourly "bell" that plays that audio. I know you can change the notes themselves in the bells.ogg file, but perhaps a bit more?
Custom kk slider music. Same as hourly music, but like a jukebox in a sort of way. Like a youtube downloader in a sense.
Alternatively, instead of the Live and Aircheck version for KK Slider, there should be a special Club LOL style that has the 8bit style mashup of all the songs mixed into on long huge medley.
This is going to be a mouthful, so bare with me.
