Further enhancements to music player required

There is a song player currently written that needs the following enhancements; 1. Everytime a song is entered, the program should set volume to 100%, and unmute if necessary. 2. The program should have a feature that if a code is entered as a track number, example :0000 it should trap that and go into a "backround" mode where it randomly chooses numbers from 1-135 and plays those songs until the STOP(*) key is pressed. the display should then say "Backround Music Mode" as the song name. 3. Possible Feature : NOT required, but nice to have. If the user enters 0 as a song name, can the program begin recording from mic-in to a WAV file called "TALK-<currentdate>-<currentime>.wav" and continue recording until the STOP(*) key is pressed. It should record to the current path. Nothing else needs to happen. NOTE: **This must not interfere with music playback. Please ensure the sound device is not locked, or anything wrong, playback of tracks 1-135 is the most important function ** Also the program version text should be updated below.
