Hi,
Thank you for your kind comments on TuneBrowser.(^^)
It seems that you attached a screenshot, but it exceeded limit of file size. Please decrease file size (like converting to low jpeg) and attach it again, if you can. Maximum file size allowed is 512 KB.
I understood “POP” means popup noise of sound (not popup window). If you are using RAMDecode to very large file, it will cause a little stop to load file between tracks.
