If you tell me the name of the songs I will gladly try. I warn you, though, I'm really slow.
As for the sound drop outs... I'm using a free version of a guitar effect I found so it does that once in a while to remind me it's free. I recently downloaded tons of new effects but I haven't had time to use them all yet. Hopefully I will find a better one once I start messing with them a bit more.
