Actually, some Songs..& Lyrics ARE sold..on-occasion.

Saw where the IRS WAS selling-off a series of Songs...formerly owned by a Writer/Publisher Debtor. Legitimately.

Less than a year ago, a Less-than-By-The-Book Producer Buddy "traded" a song he'd paid $500-for 20 years ago...to a Publisher..for a $10K debt he'd rolled-up over last year. (Not too shabby a Deal..eh?) ;-)>

So, yeah, it happens. There's some Euro Website where I've seen Lyrics..& I think maybe entire songs..(I've forgotten)...for about $20-200 each. (General Impression: ya gets what ya pays for..&..ya may get a Lawsuit if the words/etc. were "swiped-or-borrowed", too.)

Dunno if You've ever joined NSIA..(Or is it NISA..Forgot Again!) but I found them VERY Helpful, the occasional visits I made to Nashcity...back when I had some loot.
Ya Oughta Join Them...they'll crit & help ya connect AND Market Your Wares..ESPECIALLY after they know you got MARKETABLE Wares.

And they have Meetings where ya learn how to WRITE Marketable, too...if that's possibly the source of problems.

&, yeah, the Other Writers here think "Nahh..Nobody EVER sells their Songs Outright..." But, on-occasion, hey, Anything & Everything Sells...it's just a matter of Legality...& proper Negotiating..AND having a Song that's worth, say, $20-to-$10K.

Good Luck with The Game,
Best Wishes & a Big Guy-Hug,
