Spotify won't let me log in...

[battlecry21]

I'm using a different account to post this,  but I'll put in all of the right information into log in, my username, my password. Sometimes I'll try my email and it still will not work. Spotify keeps saying that the username or the password is wrong. This first started when all I did was open up the app and then it just read on my screen username/password incorrect, are you sure you've made an account? something like that. 

I haven't been able to listen to my music for a week and I'm really irritated. HELP!!! I hate these bugs and spotify needs to fix this or else they will lose their music lovers.
