in thread The $_ Special Variable

With questions like these, perhaps the most general answer is...
Learning Perl

readily available (USD 30, +//-) from vendors who include the publisher, O'Reilly, and such esteemed booksellers as Amazon, Walmart, and -- very likely -- your local independent bookstore.

Update/afterthought: your OP refers to the symbol pair 'questionmark''underscore'... and so do your further responses when Monks offering help plainly refer to the pair 'dollarsign''underscore'... which is not at all the same thing.
Does your local keyboard omit the "$" sign?

[marto]: in the sense that for various values of "a while ago" it would not have been possible (and arguable still isn't) to have a fingerprint of every piece of commercially released music to compare against.
[marto]: a co-worker refers to the late 1980s as "a while ago"
[Veltro]: Like I said before, I ment the solution as a whole
[Veltro]: People thought it was not possible.
[marto]: and until recently it wasn't and arguable (for some samples) probably isn't
[Veltro]: How did we get here? Oh yeah, advertisement. So let's get back there. What I ment to say is that I think it is possible to create an algorithm that filters out advertisement
[Veltro]: And yes, maybe your decoder needs the cloud to do so.
