Hi !

I've just made a modification to /usr/lib/airtime/pypo/bin/liquidsoap_scripts/ls_script.liq and wanted to share it with you. Works well on Airtime 2.0.1

Modifications are HIGHTLIGHTED

Keep in mind that any upgrade of Airtime will destroy this script... Keep it in a safe place.

This script will play stored mp3s in folders depending of time of the day / day of the week + jingle management with weight function when nothing is on air on Airtime. There is also NRJ effect on the output (loud and fat compression, it suits our kind of music).

Big up to Airtime team for this brillant work, I can't wait for smart playlists and live harbor features.

Here we go and VIVE LA BRETAGNE.
