Hello

I notice that certain numbered URLs are in red, what does this mean?

Also, why are there different sizes of the same song I try to download? I don't mean those that are of album or long version or in different file format. Thanks.

Not sure what you mean by "URLs are in red". Is this in your search results or do you mean files in your library? Files in the library in red mean they're not being shared.

On file sizes, be sure to check the bitrate. A file with a higher bitrate will be larger than one with a lower one. A higher bitrate should also mean better quality.

Files are sometimes cut off short and some have more that one version out, like a radio edit. Then there are the fake files, they're made to look like real files(same size, bitrate, ect) but they never d/load.

Hello 6pac

Thanks for your response. It's red as in search results. Ok I won't bother with them then if they are not for sharing. Noted on the bitrate.

Red files in your search results wouldn't mean they're not being shared. You can't share a file you haven't d/loaded yet. If it's a url then it will open up your browser to a web page. They may just be spam and you can right click on them and mark them as junk.
