Music Subscription Service
Im talking about things like Promo Only, Ergmusic etc…
What do you guys use and which do you guys prefer? And for what reasons?
NOTE: I’m looking for one that contains mostly club-type mixes of Top40 with some house and electro optimally for my own use 
EDIT: Also can you keep the music? I know things that aren’t geared for DJ’s like ZunePass or what not you can’t keep the music.
Can you keep the music if you end the subscription? Im looking more for something that lets me keep the music - i doubt unlimited downloads would let me keep that or i would just download everything i need in one month 
Promo Only is great for what you are looking for. I recommend the Mainstream Club series for top 40 remixes and all things on the more popular side of the spectrum… comes mostly in two disc sets and you definitely get to keep the tracks (they still send them on CD, although they are starting up a download service).
Top quality… been with them for a long time. The only place I still get physical CD’s from.
Digiwaxx. It’s free if you’re a DJ.
They don’t seem to have an option for the Mobile DJ 
I don’t fit in the other categories.
I use djcity.com
its kind of expensive ($30 per month) but if you are consistently making money with gigs and stuff that money is easily covered.
I look at like 10-15 different music websites every day too.
I use themixtools.com
hereʼs their blog themixtools.blogspot.com
I use 8th Wonder. Cheaper than most other services and they have video, too.
