Hi... I checked your source link 2 Mungo Jerry ...we can start with your project, but we need ALL YOUR suggestions to your needs music=what you expect 2b done from youtube source song.. things as ..instrumentation? (piano?-piano with band?) playtime of ready music?, out-file format? (wav,wma,mp3?) looped-or not (how long loop?) if you select mp3 as output file for looping - we can process it to smoothly loop without small gap by replay, the same way as you play looped "wav" - it`s technical, connected with mp3-coding problem, causing msec gap by repeat-play, but we know how to deal to remove this and get "smooth music"...
we are profi - we made over 250 projects via 3sites,
.. we are opened to talk $+time, but need your infos..
