Right, I see both sides of the coin here - As a DJ I want to play the exclusives, the tunes people havent heard, an the way the vinyl world rotates is a tricky & expensive one! The Digital music aint costing anything at the moment (long as you got internet!) and you can have a tune youve been slobbering over for months! This is where the producers lose out financially - I would pay for MP3s through a monthly subscription or pay-per-tune if i was honest.
You can hang around all day Wed/Thurs vinyl promo hunting, Get friendly with the Record shop dudes, or be patient an wait for the full releases, goddamn it!
For the CD side - Availability of tunes/freedom of what to play an the million-an-one tracks you can get in a CD wallet is very appealing.
Jus listen to New Talent, an if anything takes your fancy, get chatting with the producer for an MP3.
Type in a 'wishlist' though Soulseek an 12 hours later you got tunes you arent gonna have for 12 months!
What it comes down to is a heathy mixture of Wax & CD imo - Using a cd deck is simple, but as with everything it has its disadvantages.
alot of people ive chatted to find it hard to mix in/out of CDs without the visual of where the drop is - if you jus make a note on your cd tracktist of the time it drops an problem solved!
The Digital DJ is here to stay, but the Vinyl junkie will always reign supreme!
