Investment / Frivolous spending ?

If you know me, you have probably at some point been subjected to my love of School House Rock. Today my love was taken to a new level. Let me tell you the tale.
I went to the music store to make an investment today... I needed more lounge music... and there was a noticeable hole in my "Best of the (insert decade here)" series... I had the 50's-70's.... so today I bought the 80's and 90's. So much more music.. and I'm actually more familiar with most of this stuff! I also found a discount rack and clearance bin... so I bought some other random stuff... mostly individual songs that I might be able to encorporate into my lounge act.... such as Britney's "I'm a slave 4 U" and so on and so forth... theres a reason they were on clearance....
BUT the highlight of my day was when what did I find in the discount PVM racks..... but the sheet music for selections from School House Rock.... thats right... I can go to "conjunction junction' anytime I want now... and I can consult "Lolly lolly lolly get your adverbs here" too! Actually conjunction junction is scored in the DVD for a really awesome sounding quartet of voices... I'm thinking next year at a noon-hour recital....
All in all, I spend close to 100$ on music today. If this job works out well, I can justify that to myself as an investment... if not... I'll cry myself to sleep tonight.... again.
So heres the thing.. I now have 5 books in the decades series... and I am only going to use about half the songs in each(at best). That could make for a large pile of music beside the piano....
At the same time... the binding of the books is done with glue... so they don't lie flat on the piano... meaning it's damned near impossible to play from them....................
::::::: Festival accompanying... David.... book closing.... argh..... eeep!!!:::::::::::::
My original thought was that I should have them rebound... simple enough... they just slice off the glue and then stick a coil binding spiral in it. BUT this is my plan-
I will get them to cut the glue bound bit off.. then I will take out just the songs I want... organise them alphabetically into 2 or 3 books that I can use rather than 5! Once they are organised, I can take them back to be bound together in neat books that will suit my needs quite nicely.
At the same time, it's going to be a fair chunk of effort on my part... right now, I'm figuring out which pieces I want to use from each book.... I'm discriminating based on whether I know the piece or not as well as whether or not it would be appropriate for background music.
Fun Fun Fun!
