In the UK I'd by Best of Books, sometimes containing 20 songs, for about 11.99. I think my Beatle's Anthology with around 100 songs was around 25 quid. Download sites seem to be £2.50 a song, but I can't understand why, when distribution and printing is cheaper.
 
I never have faith in the the original key for the song either, they seem different on different sites, then you check against a guitar tabs site and it's different again. I play in C, Bb and unusually G, so I have to transpose twice, so having faith in the original key would help.
 
 

Even with printed sheet music anthologies and song books have always worked out a lot cheaper than buying individual songs.

Yeah I understand that bulk buying an 'best of' is going to be cheaper. How much is an individual  printed sheet normally, is their any saving it being downloaded?

Its a several years since I bought any but if I recall correctly it was more than £2.50 unless buying from remainder bins.

that's where the artists actually make money for their art.

FIXED for you

LOL, well it's still more income IF you have publishing rights, then you will get off of actual record sales.
 
 

A friend of mine leads a band called 'The Miserable Rich' and interesting modern folk band. When they wanted to raise funds to record a new album, they transcribed their previous work and used made it available to anyone how contributed to the new album fund. It was a good concept and approach.
 
Lyrics to songs are freely available. Guitarists can find tabs, easily enough, keyboards can find chord structures easily enough. Good musicians can work out a melody. Seems to me that the main market fo sheet music would be for beginners.
 
I have often bought best of books just for a couple of songs. I would have those songs with me here, but the stack of books is too costly to send from the UK, and I wasn't going to rip pages out. I did spend some time photoing pages of some songs I really wanted. But the cost of single sheet music, which in this country can feed me for a couple of days means I turn to less downloading sites, but not all the songs are available this way. I've even taken fragments from different samples to patch together the verse and chorus. I'd happily pay for them if i thought the price was reasonable, but I don't.

 Seems to me that the main market fo sheet music would be for beginners.

I think professional musicians who need to cover a song but do not want to spend time working things out and searching out the information would find it useful. If you are a Pro time is money, at minimum wage £2.50 is 23 minutes.

Not in Vietnam it isn't
