Ok, rather than giving you the .wav files now, which would take both of us many hours of upload/download time, I'll continue to provide mp3 files until you make a final decision on file type (Though my personal opinion is that, not only are mp3s more versatile at lower quality levels, i.e. they lose less than ogg files, they are also much more widely used.)
Secondly, there, in my opinion, is no issue with the tunes looping. They end cleanly without bleeps or clicks.
These two tunes are not designed as loops but as short songs, just like some of the RPG Maker standard RTP. I don't feel this is an issue anyway, songs which have a clear beginning-middle-end are more pleasant to listen to in general than a loop.
