I use the free one and if I want to find something I put in the artist, colon and part of the title of the song - and bingo there it is.

Hasn't failed yet.

An example.

I bought an LP years ago by a band called Aardvark (it is bizarrely quite collectable though why an asking price of £250! . The only thing I can remember is that it had the word 'very' in the title. Type in aardvark : very and the track appears.

It's hard to imagine how much easier it could be?

Try me on one of the ones you can't find...
