I try this, but it removes only the first pattern:
awk '{gsub(/^[ <option>]+|[ </option>]+$/,"");print}' nowplaying.txt

The pattern, [ <option>], only matches a single character. It matches any one of the characters between [ and ].

How to remove the last </option> field so the resulting line stays with:
Nick Gilder - Hot child in the city

Code:
awk '{ gsub( "</*option>", "" ) ; print }'

evp_pkey_print_params

EVP_PKEY_print_private(3SSL)					      OpenSSL					      EVP_PKEY_print_private(3SSL)

NAME

       EVP_PKEY_print_public, EVP_PKEY_print_private, EVP_PKEY_print_params - public key algorithm printing routines.

SYNOPSIS

	#include <openssl/evp.h>

	int EVP_PKEY_print_public(BIO *out, const EVP_PKEY *pkey,
				       int indent, ASN1_PCTX *pctx);
	int EVP_PKEY_print_private(BIO *out, const EVP_PKEY *pkey,
				       int indent, ASN1_PCTX *pctx);
	int EVP_PKEY_print_params(BIO *out, const EVP_PKEY *pkey,
				       int indent, ASN1_PCTX *pctx);

DESCRIPTION

       The functions EVP_PKEY_print_public(), EVP_PKEY_print_private() and EVP_PKEY_print_params() print out the public, private or parameter
       components of key pkey respectively. The key is sent to BIO out in human readable form. The parameter indent indicated how far the printout
       should be indented.

       The pctx parameter allows the print output to be finely tuned by using ASN1 printing options. If pctx is set to NULL then default values
       will be used.

NOTES

       Currently no public key algorithms include any options in the pctx parameter parameter.

       If the key does not include all the components indicated by the function then only those contained in the key will be printed. For example
       passing a public key to EVP_PKEY_print_private() will only print the public components.

RETURN VALUES

       These functions all return 1 for success and 0 or a negative value for failure.	In particular a return value of -2 indicates the operation
       is not supported by the public key algorithm.

SEE ALSO

       EVP_PKEY_CTX_new(3), EVP_PKEY_keygen(3)

HISTORY

       These functions were first added to OpenSSL 1.0.0.

1.0.1e								    2013-02-11					      EVP_PKEY_print_private(3SSL)
