Audition suggestion

I have a suggestion for Adobe Audition for users like me who are infrequent/minimal.  My suggestion/request is to offer a monthly service for minimal use, like the demo, for say $5 per month.  It would limit to one multitrack session per month or something like that, maybe even limit the tracks allowed per session.  Or offer a pay per day deal based on the current pricing model.  I have used this program since its Cool Edit Pro days and still prefer it to other programs for editing and mastering.  These days I only use it to upload my mp3 song file, which I make using other equipment, into a multitrack session and master it with effects in Audition.  So one track per session, and I do that once every 3-4 months.  I was on the annual (paid monthly) subscription last year and only completed 4 songs, i.e. I only used Audition four times.  That was my mistake, but it still wouldn't of saved me much money had I only paid for 4 individual months worth.  My old Audition 3 software won't work anymore either unfortunately.  Maybe I'm off base, but for me to pay $30 per one month use just to master one song in one multitrack session using only one track is absurd.  I know I could just wait until I have more than one song to master but that's not how I operate.  I like to get things done when it feels right, or before I change my mind.   Thanks for reading my rant!
