Hi, can you post ReadFullyStream sources for this example?

Hi, Can you please post other related modifications to this post including ReadFullyStream ?

ReadFullyStream is in NAudioDemo app: https://naudio.codeplex.com/SourceControl/latest#NAudioDemo/Mp3StreamingDemo/ReadFullyStream.cs

Can you please publish your MODIFIED ReadFullyStream? I cant find
readFullyStream.metaInt
nor
readFullyStream.SongName
in the link you provided!

Hi, can you please provide me with a console version of this player?

If anyone still has interest in the solution: I wrote a working code to this modified version. Just ask me.

Hi Mwidev,
Can you please share the working code with me?
Also, do you know the site where I can get different .pls links?

@mwidev I'd be grateful if you could provide this code
